Hi, i just lost my virginity and i am worried. i am a male 22 year old. and as soon as my gf performed oral sex (first thing she did) i cam immanently. Then i had to wait about 5 minutes and do other stuff to her to re-gain my erection which i did, and then i lasted about 20 minutes straight, but this time my erection was not very good, kinda numb until the last few minutes. i am worried, what can i do ?
