Scar tissue

[PatPhoenix]

So, having a new partner with a different penis [see threads passim], I suddenly find that during sex I'm occasionally experiencing a sharp pain in my perineum where I had a second degree tear repaired. 15 years ago. I'm guessing this is scar tissue?

Is there anything I can do about it? Massage?

Yes, probably scar tissue and massage and regular stretching should help. If it doesn't there's a small operation called a Fenton's procedure which removes the excess scar tissue and cure the problem.
