i was having sex with my boyfriend at the weekend, he quickly went inside me and came out a few seconds later within a split second there was blood EVERYWHERE, hes later discovered that he has torn a a bit of his 'banjo string' not completly but slightly. He's told me he will be fine and is hoping it will heal without any treatments. he can just manage to pull his skin back but is finding it very painful and fears that when he is erect he will not be able to pull it back atall as he already has pain issues when doing so. Will it heal without any help and how long will it take? Is there anything we can do to prevent this in the future and will he have issues when erect?
