At the moment, it was age 46, but I hope it doesn’t stay that way. I always had a very high sex drive and can tell all the smug 30 somethings that have answered this thread in horror saying “I hope this never happens to me!” - well, it might.
I was like you, probably worse, my sex drive was all encompassing, my weekends were spent finding cute guys to sleep with or enjoying my boyfriend in bed, it was pretty much the main drive of my life, sex was a priority more than any other basic need (I was told I was “just like a guy” in this respect, pity them if so, it wasn’t healthy!)
Fast forward to now, I had a child late in life (having too much fun before!) with a wonderful partner and sex is not in the picture for several reasons, we’re knackered, there’s a child in our bed, we have no time alone, we’re both tired and cranky, he is a little older - but I have to say the main point that no one seems to have said before -
Having sex with the same person for X number of years can be a bit boring!!!
Sorry to shatter the illusions of the 30 somethings. Sometimes a woman can not want sex with her husband, not because she has gone off sex, but just because she has gone off sex with him - he isn’t terribly exciting, even though she loves him to bits and would never want to cheat on him at all. So the libido does die down.
I think it might be worth checking all the “I’m 70 and had a massive session this morning” with the question “how long have you known your partner”? Surely we all know novelty is a massive turn on, no matter what age?
