My preferences...
Aesthetically I like big dicks with trimmed pubes, like if I'm looking at porn. In reality, when I fall in love with a guy, I usually accept his dick no matter what it looks like, within reason. I'm demisexual so it's impossible for me to not accept the entire person, when I'm dealing with a real live person. In terms of straight up objectification, I like bottoms with average to big dicks who are toned to muscular. I tend to end up with mesomorph (stocky) build type guys who have big dicks, not sure why. And that same body type tends to be into me because I'm tall and slender with a big dick. I guess we all want the body type we don't have. My main requirement for sexual partners is that they can take and enjoy a big dick. If they can't there's no point.
In terms of manscaping, yes... please keep that shit trimmed. I don't enjoy giving BJs when it's untrimmed, and I will not give attention to his balls if he hasn't dealt with his hair. Ew. For myself, I keep it trimmed year-round. It's just cleaner. Every guy I've been with who has a big bush always has a faint smell of crotch rot, no matter if he has recently showered or not. I can't deal with it. And if a guy is uncut, having a full bush amplifies smegma smell which is an instant end to sex for me. I shower daily and in the summer it's sometimes twice daily.
To the OP... in the gay world I have honestly never met anybody who enjoys the aesthetic of small dicks. Like, not once. Everything is supposed to be supersized: muscles, dicks, butts. It's absurd really, but it's the truth. The reality of how that plays out in the bedroom is quite different. Lots of guys have dick preferences that are quite different according to getting fucked. I once dated a guy who rejected me because of the shape (not size) of my dick! He claimed it would hurt so there was no point. There are guys out there who would really appreciate you though. You do you.
