hi, saturday morning i had sex with a sex worker, i had sports activity the whole day and at night i went to drink and dance so i was really tired my penis was not even fully erect when i had sex, after 45 mins i was unable to discharge any semen also, she gave me oral before the intercourse but i didn't have a proper erection but what struck me was when the woman went inside to take a shower after the sex i got up i found the condom on the floor near the side of the bed, now i know that i did wear protection before having vaginal intercourse but i think during the intercourse my penis started to shrink because i was too tired and when the women got up after the sex the condom was on her and she was the one who dropped it on the side, because i was intoxicated i didnt have much sense then, but the next day i have been scared as hell, please drop some suggestions.
