nah, ive never done a mmf. it doesnt really bother me though. i did have the opportunity but i wasnt ready for that at that time. i have flirted and teased guys who were interested in me, ive been propositioned a jillion times. but as far as mmf goes, it hasnt happened. i have been fffm and i have had guys whack it while watching a girl give me a bj, and i have had sex in front of guys a couple of times but never have i done anything with them.
i just dont find guys attractive. if i did, hell, id try it, but guys.. they are jsut not hot. in porn, i can appreciate a nice looking cock (an ugly one will ruin it for me) and seeing cum is fucking awesome and i love it but thats where the line ends. and no, im not ashamed of it.
