I love anal, I don't know why but it drives me wild. It's taboo enough to make it less common without being super crazy, it takes more dedication, intimacy and teamwork and being comfortable with a level of vulnerability to enjoy than normal sex, and it feels great for both sides if you get it right. If a woman trusts you enough to do anal that's a big deal and a turn on in itself.
Sex is great, but its more common, less taboo, less wild, and less work. Sex is like a handjob compared to anal I guess.
I dunno, I like em both, but when anal is hinted at, something in my brain pops.
Otherwise, other than sexy outfits, I'm pretty vanilla and don't "get" a lot of kinks. I don't know why you'd hit someone you love and call them names, I don't know why you'd pretend to do thing non consensually.. and those arent even on the wildest side of kinks! Nappy/baby stuff? Nope! Furry stuff? Nope! Vore? Unbirth? Hentai of little girls with the often used excuse that they only "look" young? Incest? I don't get any of it.
Many of these things seem like they should be discussed with a therapist and not harboured and defended as a kink, but I like looking at buttholes and shoving stuff in em so who am I to talk.
Hell, you could even question general sexuality further and say I don't understand why people are gay, why people are trans and why people are asexual, because my own personal experience is that I'm comfortable in my male body, think women are sexy and I'm horny all the time. I don't GET any of it, but I understand that everyone is different, and unless you're hurting/abusing someone with your actions then who cares, just be happy doing who or what you enjoy. Who am I to judge anyone.
Everyone is a unique individual with their own likes, dislikes, history with ups and down, and things they're good and bad at, and a million other dimensions. You are not defined solely by the thing that floats your boat.
I like buttholes but I'm more than just a butthole guy. I'm also bad at team sports. We all have dimensions.
EDIT: I could have just said "poop stuff" but this comment really got away from me.
