Im 18 years old and the other night me and my girlfriend were playing with each other sitting on her couch and the first time she put her hand down my pants and started messing with me I got really hard really fast and it was feeling great then she stopped for a little bit probably about 2 minutes because her hand was hurting but when she started again I couldn't get hard but when she put it back in my pants and started jerking me again I started getting hard then right when she pulled it out it went right back to being soft she kept trying for a couple minutes to get me hard but nothing so I eventually just told her to stop I was really embarrassed about this I've never had this problem before. I'm just wondering what could have happened I also masterbate a lot mostly every other day could this be the cause of it I just really want some other peoples views on this
