Have encountered this problem previously?

I have an accident last night with a girl met at the party. All was ok but at one moment my dick `s did not get up. What can it be? Help!

You were probably too drunk or maybe you really liked the girl and so you were stressed. And stress can be problematic if you put too much pressure on yourself to perform well sexually. You need to relax and things will come naturally. It has happened to me once before so try lots of play and preliminaries maybe?

Good luck man!

Sometimes such happen. Your girlfriend can excite you if such flaccidness happen. Usually it is psychological
