While I can get an erection with no problem at all, I find it hard to regain it once it's gone. And this becomes a problem with foreplay. I initially get hard during making out and grinding, but then I lose it when the clothes come off and I go down on her for a while. Then it becomes hard to get it back, even if she goes down on me. It's like how a person can fall asleep easily, but when they get awoken, it's hard to fall back asleep. Does anyone else have this problem or some advice? I don't want to not go down on her first coz I love doing it and she likes it too. Thanks.
