I have never done threesomes. I thought that once you do engage in threesomes you sort of cross the line and it is hard to go back. Especially if you initiated it. I think your bf must be very confused by the mixed message you are sending him.

But the general answer for true delusions is to take an AP. That would open up the possibility of side effects including weight gain, so definitely not "free".

It is not clear though that you are having true delusions.

Maybe you should try an AP to see how you respond?
