Hello, I Have A Question About My Foreskin Tearing (I'm

Hello, I have a question about my foreskin tearing (I'm uncircumcised). I noticed it thethe time I was having sex. I, noticed a slight tear at the base (underneath?) and started bleeding where it seems that there's a middle line (frenulum?) joining up with the foreskin. The initial irritation seems to have gone away for a couple days, but today while examining again, I noticed that I inflicted some damage just from self examining. I'm worried about when my fiancee returns from overseas, will it again tear during intercourse? Any advice/information?
If it is not errect my foreskin is allright but when its errect it starts hurting if I unfold the forskin plesse help...
