Decisions ????

So there are two guys who want to fuck me at the same time.( not like a threesome unless they're down for that 😋💦). They dont know about eachother but they dont really need to know cause its just casual sex. One is a really good friend . The other is my ex boyfriend who complained about his girlfriend not being able to ride him how he likes it (i was a little sceptical about this but its just one time). Should I fuck them both or choose just one??? Please no bashing.
