Sex is very important to me, but my boyfriend and I haven't had it in about 12 years. It started with him losing interest (he says because of how he feels about his body, even though I told him it doesn't bother me), but then my sex drive diminished, and even though I want sex mentally and emotionally, I physically don't desire sex too much. Sex is also painful to me, and I've had several gynecologists give me several different answers, but nothing's helped.
My boyfriend and I have been together for 18 years, and while there are parts of our relationship that I don't feel we're connected, we do connect in other ways and we have a strong bond. I don't know if this answers your questions, but it's what I can tell you.
