Over the past few months I've gotten to the point where I don't want to have sex anymore. It's very strange for me because it used to be one of my biggest desires. Let me try to explain. 

Since I've been 18, I've had quite a few partners. I've never NOT wanted to pleasure them, and I've always gone to great strides to do so. I've owned equipment that could fill a dungeon and at the smallest opening I would leap to make them feel good. Now, I dont feel that way anymore. 

I've been trying to get around it lately, but I feel sick when I think about having sex or pleasuring my partners. Sometimes it makes me genuinely want to throw up. I found someone who matches my sexual needs, but now I'm changing into someone who doesn't want it at all and I hate it. Why am I getting so sex repulsed? Also, no it isn't just her. I started getting repulsed with the girl prior as well. 

Tl:dr I used to be a sexual maniac and now I hate when thinking about sex. What do?
