i have been with my partner 3 years and i love her very much but over the last year i have had no interest in sex at all, i know its not about my partner because i still find her very attractive and i love to be around her i just have no interest in sex, i have also found this to be a pattern through out my life with every partner i have been with, as far as i'm aware i'm not depressed or stressed out about anything. I don't understand why this continues to happen when i am the happiest i have ever been, sex has never been a big deal to me and i was a late developer it's was always something that never interested me but my sex drive was really high when me and my partner first met and now it just don't exsist and i know she is feeling it, has anyone got any ideas on what i can do to sort it out as i think this may cost me my marrage
