While I consider myself versatile, I love to mostly bottom. To me there's nothing better than feeling a hard cock sliding deep inside my ass. Just massaging my prostate for a while will give me the most mind blowing cum you can imagine.
While I consider myself versatile, I much prefer to bottom. Don't get me wrong. If my partner wants my cock in his ass, I certainly wouldn't turn him down. For us I'm guessing I bottom about 3/4 of the time.
