yeah, we've been together almost a year and we have sex about 1.5 times a day on average (some days none, some days lots and lots). We use a lot of positions, and we both love girl-on-top
I have to tense my thighs and buttocks to come some times (esp. if we had sex recently), so if my legs get too tired I just can't come.
when we have sex frequently that's when it's hard for me to come.
i guess my opinion on the subject is "If I can get it up...I want sex!" I don't really care if I can come or not.
do you as a woman feel bad when your man can't come?
