i am an uncircumsized male and i frequently masturbate , especially in the mornings. i don't really use lubrication for this and had been doing it more frequent of late and i had noticed that i was working the head alot (it takes me a long time) and it was a little sore, a few days after i noticed the tenderness me and a guy had sex and he did'nt have any lube and inspite of this we had sex anyway(i'm like a camel it had been like 6 months) and it was kinda painful because of the tug of the skin being pulled back, (this always happens especially when i use a condum) during intercourse and i've noticed in thespot where my foreskin joins the penis at the head was really sore for a few days afer that and it looked like i had a rugburn. It's been a couple weeks and i've had intercourse again (with lube) but we were kinda rough and the head is still kinda of red.It does'nt hurt to pee or anything and i can touch it and it feels fine but it's still pretty red should i be worried? (i have made a slightly succesfull effort to curtail the masturbation)
