First off, can you tell if your boyfriend has masturbated before having sex with him? Let's say, within a couple of days or hours?
Secondly, Why does he HAVE to do it?
My girlfriend is 28 years old and I taught here how to masturbate (on her own). She told me she did not masturbate before and now she loves it and she will masturbate when she misses my company and our sex.
I've been married for nine years, and have two kids ages two and four. I've only had one orgasm my whole life, when my husband and I first made love about 12 years ago.
I have been with my boyfriend for a little over a year. He is 40 and I am 35. When our relationship started out, we were very sexually active. We would have sex every night even in the middle of the night.
