I recently started seeing someone and we have sex nearly everyday. She is on a form of birth control and clean, so I don't wear a condom, which is a first for me. Another first is that I can actually come inside of her. It's something I could never do before, I think because I am not sensitive enough wit a condom on. So, here's my problem: Until recently I would last a REALLY long time, much to my and others dismay, and now sometimes I come fairly quickly-enough time for her to come but completely out of my control. The other thing is that I have been having trouble getting hard for intercourse. I get hard randomly, when I see something I like, but when it comes time to penetrate I need a lot of encouragement. And then I come faster than I want. A week or so ago I started using horny goat weed which I think is responsible for my increased sensitvity, but I'm not sure. Any thoughts?
