So Me (19M) is like facing a problem with my erection which ik sounds very weird for a 19 year old but it's nothing like ED Or something. Let me explain soo this first happened when me and my ex were having sex and then we stopped for a second and I started fingering her like crazy giving it my all now what happened because of that is that I got sweaty and I started to feel the heat and I fucking lost my boner she tried giving a bj but shit did not work . And yesterday some similar shit happened with my new girl I read somewhere on Reddit that you should first finish off your girl by fingering her and obv going down on her which I did I was rock hard during our make out and shit but I fucking went crazy with the finegring she loved she finished was turned on like crazy she pulled my pants down and boom I was soft she literally didn't know what to do and started kissing me hoping I would get hard but :(. So any thoughts like why this happens? Or is it just me?
