Sex might end my relationship - please help!

[Cuddly]

Cuddly I know - the reviews are awful, and if I had known before that it would mean these consequences, I would never have used it in the first place. It has part of me wondering if I will ever enjoy sex again.

I'm sure you will. Just give it the time it needs to heal and you'll be fine.
As for the horrible sideeffects, think of it this way; genital warts for life or a month of hell? You owe it to yourself and all your future sex partners to get rid of them. Both so you can enjoy sex fully, knowing that you are not spreading STIs, but also so that they don't have to go through the ordeal that you did not.

You've done the right thing, for sure.
