Have you read back through the postings here to find the explanation of your situation (and many other things which you probably didn't realise)? You really should.
Certainly, you do want your foreskin to operate properly, to pull back and move freely during sexual intercourse - which I presume from your observations, you have not experienced yet though you certainly
might have - whilst it is probably
nicer if it does so, it is certainly not
essential for it to do so, for you to have intercourse.
And of course, you already
know that it is not at all necessary - in fact, it could almost be a disadvantage - for you to have your foreskin pull back to masturbate with perfect satisfaction.
The
big question is -
given that you are 18, that you have been masturbating for some six years or so, why is it suddenly necessary
now that you "have to pull back my foreskin to wash the head"? That's what puzzles me. What is it that happened? I'm really curious about this!
