Not sure if this is the wrong forum or not, so please feel free to move the thread if necessary. Ever since my sex life started I've had this issue where when I am about to cum I lose a certain degree of my hardness. It varies, but usually it's noticeable enough that it bothers me or it has been so bad at times that I'd have to stop (I'm a grower). It only happens when I'm having sex though; everything is fine when I do it myself. My current GF and I are used to it by now and just adjust around it, but obviously if the problem can be fixed I'd love to make it better.
