I get really hard in some positions
So last weekend I was masturbating while sitting on the side of my bed. I cannot explain it, but I was inexplicably hard. I never and I do mean ever get nearly as hard. I felt like I was going to explode, it was great. I think that when I have sex with my girlfriend I’m not at 100% erection like I was at the side of the bed, unless we have sex while I’m sitting at the side of the bed. When we do it’s great.but I ALWAYS want to have a hard erection when we have sex. What should I do? Sometimes during cowgirl or reverse cowgirl I cannot stay VERY hard and I barely feel much, she does though. I don’t even feel hard, but she is able to feel it. It’s really weird.
