I am 23 old unmarried guy. Last 2 month back, I went to have sex with call girl andi drunk lots, At bed room, l removed her clothes, she became nude and later I have also removed my all clothes. After seeing her, my penis was not standing properly. It stood up for some moment and I pushed my penis (Have used condom) into her vagina but only my penis tip went inside to her vagina and it went down. After some time, I tried to bring it up by masturbate and till that time, the sperm came from my penis and again it doesn t standup down. So we didn t have sex. At last my sex was 100% flop. I m soo tens now, my penis is not standing yet,nd the other thing when i was sleeping then my penis standing up I don t understand. still why penis is not standing up? I am much worried about it.. what precaution s should I have to take for this problem??? Please help me
