I love sucking cock and getting rimmed, and depending on the chemistry, eating ass (will get me hard every time). My def of a Vers/Btmm means begging for it on all fours and/or thrusting in rhythm behind you; in front of a sling (does anyone have one?) as well as in it. Other turn ons: good kissers (PLZ no tongue stabbers); body contact (whatever happened to foreplay?); watching (making?) BB porn; reciprocal massage (again foreplay), showing off w/video and pics. AND above all is always mutual respect.
Otherwise I like to bottom. :-P
