On a separate note, I suffered from anal fissures for 3 years, horrendously painful, like someone shoving a knife up your bum ever time you go for a poo - **** the GTN, go for the diltiazem
%. I mean, it didn't work for me overall and rid me of the fissures but my bum was very tight and needed surgery. Just don't suffer with it! And also if it happened as a result of anal sex don't beat yourself up about it, no matter what your past you have a spotless future.
