this is what me and my girlfriend did make sure you don't have a bowel movement if ya do get that out of the way next take a shower and wash that area really good next go to the bedroom and place a towel on the bed cause there is still a chance of an accident from there it's fun time make sure to use a finger first with a lube like
Maximus - Lubricant - EdenFantasys don't go for the full penis right of way go 1 finger then 2 work your way up to where penis can be insterted
just want to add if ya fart don't be embarrassed if ya love each other enough u guys can giggle about it later
people have different ways of doing it thats just how i did it
