Thanks for the compliments on my blargh! *u* I try to answer asks thoughtfully and respectfully and expect the same consideration back from whoever reads my answers ^_____^ 

As always, #your headcanon may vary, bc we’re talking about fictional vampires, they are not people. Whether you consider them to be people in their own world is up to you. For me, I see them as ex-people. They share a supernatural parasite that gradually eats away at their mortal parts, replacing it with its own immortal substance, perfecting their host bodies to its own design. So they exist beyond the definitions of sex and gender for me.

I do not believe the vampires are canonically capable of penetrative sex but do I love fanart/fanfic/RP where they have penetrative sex? YES, YES I DO, MORE PLZ. Have I commissioned such fanart of it for myself? Y E S. Will I commission more of it or write my own in the future? YOU’RE GOTDAMN RIGHT I WILL. I love the creativity of the fanon interpretations and I will support these ideas forever.

According to Lestat vampires don’t feel sex drive, 

I don’t recall anywhere in canon where Lestat says that vampires do not feel a sex drive. He has described himself as a sensualist, and we know he falls in love easily. I think that they do feel a sex drive, just not in the genitally-penetrative sex way (not the most eloquent phrasing there but I can’t think of another way to put it; “PIV/penis-in-vagina” just doesn’t apply to most of our gay ships). 

Turning vampires seems to be their ultimate “sexual” act that they can perform, bc it is equivalent to pregnancy (a fledgling is being “born to darkness”), and it is always described primarily as the sharing of the Blood between maker and fledgling. I headcanon that Lestat loves the act of performing this, and that’s partly why he has had SO MANY FLEDGLINGS. So I believe that they still do feel sexual lust, it’s channeled through the experience of taking/sharing blood, and other sensually physical things.

In fanon there is a wide spectrum of whether they can have genitally-penetrative sex, some even speculate that their um… output… would be very bloody. There is fanart/fanfics/RP/etc. in which they can have that kind of sex, and ones in which they cannot. 

in The Tale of the Body Thief one of the things he wants to expierence when he has a human body is sex because he says this is something he can’t do with his vampire body. 

^This is up to every reader’s interpretation, and yes, in my opinion, Ricean vampires in canon cannot have penetrative sex. My main evidence for them as being unable to have genitally-penetrative sex comes from [hit the jump for spoilers]. 

AR has written alot of other novels with genitally-penetrative sex being an important factor, so I doubt it was an oversight in denying it to her vampires. If you want to go by her as the authority on her novels, and many ppl do, she posted definitively about it when asked about Daniel and Marius in PL:

AR does not go into much further detail than that, even in canon, other than the fact that the sharing of blood is more intimate for them than than simple mortal penetrative sex. Part of why she chose this may be to avoid the issue of pregnancy the way mortals do it; a baby cannot grow in undead flesh, y’know?

TL;DR: Personally, I headcanon them as unable to have genitally-penetrative sex. There are human couples who are unable (or do not want) to experience genitally-penetrative sex, and they can still be sexually intimate with each other in other ways. So it’s partly in how you define sex and intimacy. 

For more on this, I have these tags: #asexuality, #asexual, #sex, #sexuality, #lets talk about sex.

But in his book Armand mentions that he had sex with Marius several times.

Armand was mortal for some of that book, and Marius did sexual things with him, but not genitally-penetrative sex. After Armand is turned, Marius and Armand have an intimate moment with a mortal woman together, but again, it is not genitally-penetrative sex for them. 

My main evidence for them as being unable to have genitally-penetrative sex comes from:

• Louis’s description of sex in IWTV:

Claudia asks Louis about sex in IWTV, and he replies that it “‘…was something hurried…And… it was seldom savored… something acute that was quickly lost. I think that it was the pale shadow of killing.’”

^He’s talking about it as occurring in the past, I think he means when he was mortal. Here he says it’s not equivalent to the act of taking blood from a victim, sex is a lesser experience for him.

• Lestat’s description of his non-functioning Priapus in QOTD:

“I studied my reflection … and the organ, the organ we don’t need, poised as if ready for what it would never again know how to do or want to do, marble, a Priapus at a gate” – Lestat, Queen of the Damned

^This quote has been interpreted over and over again as meaning many things, one of which being that the vampires have a permanent boner, which I disagree with. I highly doubt Louis, someone with a lot of dignity, would be fine with walking around for eternity with a permanent boner. I blame this misunderstanding on the translators who translated “poised” to “erect” in various other languages.

I interpret that quote as meaning that his Priapus is just “waiting.” 

• and Pandora’s description of Marius’ non-functioning (but very hard) dick in her book. Pandora wants Marius to sex her up on their ‘wedding night’ and he can’t do it, but they try, awkwardly:

He covered me and kissed my cheek. “Drink from me,” he said, “drink until the pain goes away. It’s only the body dying, drink Pandora, you are immortal.“
“Fill me, take me,” I said. I reached down between his legs.
“It doesn’t matter now.”
But it was hard, this organ I sought, the organ forever lost to the god Osiris. I guided it, hard and cold as it was, into my body. Then I drank and drank, and when I felt his teeth again on my neck, when he began to draw from me the new mixture that filled my veins, it was sweet suckling, and I knew him and loved him and knew all his secrets in one flash which meant nothing.  He was right. The lower organs meant nothing. He fed on me. I fed on him. This was our marriage. –Pandora

I think AR is telling us that in order to be immortal, a great sacrifice must be made. Not just outliving your loved ones, food and drink, sunlight, and your appearance being altered. For many people, sex is as necessary to life as eating and breathing. To give that up for eternity is a huge sacrifice, but, you do get super powers an immortality. Fair trade?
