A stripper offered to have a threesome with my bf and I. We have her number. I'm a little worried about a few things.
- Is she clean? How will we know and how can we be safe?
- Is it automatically assumed that we would have to pay her?
- Any suggestions from others who have encountered this or who have had been in similar situations?


You will not know whether she is clean. It's just a risk you take having sexual relations with anyone you don't know (and some you do). You can be.safe by using condoms. That's probably all you can do.
Yes, she expects to be payed.
If boundaries are set it can go smoothly. Agree on a price beforehand. Tell her what you expect to get from the experience. Tell her how far she can go with your boyfriend and also with you.Go down to the hotel bar and have your boyfriend buy you all a round of drinks beforehand. Keep an open mind.
