Ah, see, that would be a problem. Masturbation is an excellent way to let off sexual steam. Personally, I didn’t say anything because I thought you had been doing this and the erections still came frequently. There are a fair number of taboos surrounding masturbation, even for men. As a female, I’m not sure how much insight I can offer into the subject, but I can tell you a few things.
1. It is not shameful. It is a perfectly natural bodily urge and an extremely healthy way to express one’s sexuality.
2. It feels pretty damn good. True, it does not feel as good as when someone else is involved, but don’t sell it short either.
3. It is a proven technique to get rid of erections. If you still have an erection after you masturbate (as in, a little while later, not immediately after) then there might be some medical cause behind it.
Personally, I am completely in favor of masturbation for all of the reasons I listed above and more (except for the erection thing cuz I’m female). I hope this helps.
