Depends what you want from the punt I guess
I had a similar problem about a month back when i booked a girl then bit the inside of my mouth the night before the punt.
So I wouldn't have booked a girl having done that however the booking was already made so I went through with it and avoided
any kissing and RO due to the risk of catching something, she was a regular so DFK etc wasn't a must have as i've already been there.
Still able to have sex and get a BJ if you are really in need of a leg over and no DFK or RO isn't a show stopper however if it is then better safe than sorry and don't go through with the booking
