i m 17 and i have been sexually active for around 5 weeks now, using contraception and not using contraception. but on friday night i ejaculated in my girlfriend for the first time. on sunday night/monday morning i started to get this tickling feeling where my foreskin attaches to my helmet... it s wednesday now and hasn t gone away. it comes on mainly at night but also when i m masturbating it tickles and feels uncomfortable. the tickling feeling doesn t hurt or anything, it s just uncomfortable and I m worried as to what it is. could you please help. thank you
