I had sex with a girl about 2 weeks ago and a week after doing it the hair around my penis has been really itchy off and on. Around the same time somebody pulled real hard on my hair down there. I used a condom when I was with her. Is it possible something could have been passed or just a irritation. Nothings visible and everything looks ok.
I had sex with a girl and got a huge rash around my cock and it was itching like hell, turns out it was the hand cream she was using on her hands when she was wanking me off
It could, as BIGMIKE suggests, be an allergy; but alternatively she may have passed on a fungal infection or pubic lice or scabies. These only need pubic skin-skin contact.
Fungal infections need an anti-fungal cream; pubic lice or scabies need an insecticidal cream. Both should be available from a pharmacy without prescription.
