Having issues with my sex drive. I don't think I've ever been sexually attracted to anyone to the point that I feel the need to have sex.
I have had sex. I have enjoyed it. I just never feel the need to do it and I could live my life without it.
When I do have sex it takes a very long time (hours and hours) to the point where my partner just gives up and I feel bad for not giving them the satisfaction of satisfying me.
I am in a happy relationship, and this has happened in every relationship or sexual encounter I've had.
I feel guilty because my partner gets upset about me not wanting it and etc.
I really would like to know what it is, or maybe be able to get some ideas of what might be wrong with me.

I haven't been to a T about it yet, but when I go I'll explain it to them as best as I can.
