Some women seem to be so upset if their partners masturbate.
Hey, it is OUR dick!
I've been seeing someone for about 6 months and we have sex probably about 6 or 7 times a week. I still masturbate, though. Mostly it's because she isn't always around when I'm horny. But another reason might be because I have a lot of fantasies that she can't always fulfill. Sometimes I wonder if it means I'll leave her eventually, but then other times I find that I wouldn't actually like those fantasies if they came to life because real life and fantasies are quite different. I've learned to meld some of my fantasies into my sex with her and she's always into it, so it works out.
