I am male and in a relationship with a woman that provides a nice companionship, but it has never been very sexually charged. I have been in this relationship for 3 years, but I have never had major sexual urges for the woman that I am with. Prior to this relationship, I had a rather high sex drive. Recently, I was diagnosed with low testosterone (Total and Free = 289 with range 250-1100 and % free testosterone = 1.35 with range 1.5 - 2.2). I realize that low testosterone can play a factor in decreased sexual urges or libido, but can the converse be true? That is, can a dull relationship (sexually speaking) actually cause your testosterone to diminish?
