Re: Too much masturbation??
That's probably exactly why she did it.
You could try cutting down on it, just to see how it goes, but it could end up back-firing if she comes to feel like she is just servicing you. And believe me, there have been enough posts by women who feel that way about sex w/their partners sometimes. It seems like there can be such a fine line too. And there's no guarantee that an arrangement that's perfect for one couple will work for another, or a different partner.
Anyway, I also think this is something she will get over with time.
Out of curiosity, how would you feel if you had a gf who was still masturbating behind your back? And what would you think of the possible reasons she may be doing it?
