I've been in a relationship for about three years now, we used to have a mutual sexual drive, since I've moved in he has not been interested at all! He is on dating sites I've found it, he masterbation almost nightly and is hiding watching porn. I think the worst, could use some advice. Should also add, we are not real Young, he's 55 and I'm 50, both are in pretty good shape for or age. I throw in the towel and give up? Derae
