I don't know if you're male or female, but I'm a fan of compact butts on both (big butts on men are one of my biggest turn-offs, in fact). Funnily enough, the subject of my butt came up here recently, and I have been told more than once (not by people here, who haven't seen it) that I have a great ass, and it's quite small. Normal, decent men don't obsess over big asses; any man who picks on your butt for not being huge is a loser of the highest order. As for the shitheads who are saying, "You work out, how come your butt isn't any bigger?" Tell them to fuck off. Or, if you want to go the polite route--which is what I generally do--try this: Look confused. Say, "What?" and make them repeat it. Make them repeat it several times. Act like you don't understand the question or why they're asking it, like, "Sorry, are you asking me why my butt isn't bigger? Why are you asking me that?" By the time you've made them repeat it a couple of times, and looked genuinely confused about why on earth they would even ask a question like that, they'll usually have realized what a shitty, offensive thing that is to say and will back down (again, usually). Hugs to you, no one should be making you feel ugly for having what is probably an adorable, tight, firm ass.
