My girlfriend and i have been together for about 2 and a half years now. I love her to bits and want to spend the rest of my life with her but for the last year our sex life has been very rare or virtually non existent. She has lost her sex drive completely and mine has diminished a bit. We used to have sex all the time. We couldn't keep our hands off each other, but now we are lucky to have sex every couple months and when we do we don't seem to have the passion we used to. I still want to have sex but not as much as i used to. How can we rekindle our sex drive and bring some spice back into our relationship?
