I can’t agree with you, bc I’m not sure if you’re being silly, in more of a Tumblrland Hyperbole™ way, but I’m feeling like defending him a little.
In general I don’t like to categorize characters as one thing, they’re multi-dimensional, and they evolve and change through canon, despite their physical appearances staying the same.

[textmeme by armandromanus, who deactivated so I can’t link to it] ^This is really perfect for this conversation, bc you can tell by the expression @armandromanus chose in that pic that Armand does know that others often perceive him purely based on his looks, and how very wrong they are to do so.
It’s kind of sad to see such a rich and layered character so often reduced to a sex object. There’s a lot more to him than that. He struggles with the concept of intimacy bc it’s not just about sex.
I don’t think Armand thinks of himself as just some sextoy regardless of how many ppl offer him sex even now; he’s actually very selective about those he allows to get close to him physically and emotionally, when he has the independence to choose.
There are a number of times in Armand’s life in which he has been ravaged, totally against his will, just because of how he looks or acts.
Any Armand RPers are invited and welcome to add onto this.
A few thoughts on the quote you selected, hit the jump.
You might also be misreading that quote, it doesn’t seem like he’s admitting that he deserves to be treated like a sex object, more that he seems to be calling ppl out on their assumptions about young boys deserving to be treated like sex objects, and not requiring as much respect as an adult. He takes issue with the fact that since someone calls him “a guilty cunning child,” he deserves to be “ravaged”.
“Everyone would have a laughing boy who knows his way around the block […]”
^This sounds more like he’s saying, “People want a lover who’s easy to please and/or will happily serve skilled sex…” Basically, a prostitute, for free.
“but young boys? They’re not like men, are they?”
^This sounds more like he means, “young boys don’t need to be treated with the same respect you would treat an adult.”
