None of the women I was with was into sex that much. It was quite common to go for a week or more without sex. I thought all women were like this since I’ve never been with a woman where we had sex more than a couple of times a week. That was for very short time periods.
So if we didn’t have sex during her period, that was the same as not having sex during other times. It just was never an issue.
Now you report that he gets anxious. I say, too bad. You don’t have to keep a guy from being anxious all the time in order to hold onto him. You do what you want. You don’t owe him sex whenever he wants it. Of if you do, then damn it! I’ve been doing it wrong for thirty some odd years. But it’s just not in me to demand sex. If my partner doesn’t want it, then I don’t want it from her (which is not to say I wouldn’t want it from someone who did want it).
I wonder what would have happened if I’d found a pliable woman who would have given me sex whenever I wanted it. Maybe I wouldn’t be crazy? No way to know. But I doubt it. I think men should learn to deal with it if their partner doesn’t want sex at the time. Take no for an answer.
