Hi. My wife and I have been married for 23 yrs and when we are both in the mood, the sex is unbelievable. My wife's attitude towards intimacy has always been very conservative and it seems that she could go for weeks without feeling the desire for sex. She is a vegetarian and seems to be tired all the time. Over the years I have learned to be patient until she is in the mood or sometimes will just come out and ask her for sex. Another issue is that her period usually lasts at least 7 full days, sometimes and extra day or two. About the only time I know she will have the desire for sex is right after her period. If I don't initiate sex during the less than three weeks she does not have her period, I think we would only be intimate once a month. I think she would like sex more often, but between her period and being tired, (and the kids) the infrequency is very difficult for me. I have tried many times to discuss this with her, but we always end up in an argument and I end up feeling like I am a pervert for asking for sex at least once a week. What happens around the end of my wife's period that increases her libido? Is there a safe product that I could buy that would increase her libido at other times during the month? Any thoughts about how to increase my wifes sex drive would be greatly appreciated.
