Hi I'm a 17 year old uncircumcised male and i recently became sexually active with my partner the first time we had sex with a condom and i had no problem with my foreskin going back to normal, but the second time we had sex without a condom (she is on birth control and were sure to be as safe as possible) afterwards i noticed that my foreskin would not cover my penis entirely like before, there is very small opening that is left and it is sometimes uncomfortable when it rubs agaisnt my clothing at times. I can still at stretch out my foreskin and retract it perfectly fine, but there is just that tiny little bit that is uncovered. Please help inform me on what might be wrong.
