I'm bisexual to start this off. But is it ok to have a girlfriend and a male friend with benefits at the same time?

Okay is subjective.
Other people might think it's okay, but I think it makes you seem like a dirty whore. :D

No it's not ok, same as cheating.

What if my girlfriend knows it? And is ok with it?

>>5 then it's an open relationship? You could try a threesome too.

Well that would be nice

>>7 go for it! Talk to them about it and see where it takes you.

These kinds of things are best left to the people involved in them. It doesn't really matter if any of us on the internet disapprove. If the three of you all know what's up and are comfortable with it, then you can make own choices. Just don't be keeping anything secret between all of you.

There is the iffy territory of leading on there though. Someone might get the wrong idea and develop unwelcome feelings. It's all dependent on the specific people involved.

You can do whatever you want. if you want to have 20 boyfriends and 30 girlfriends at the same time, you can. just dont get caught!

I say listen to what >>11 says and nobody else

-_- if your girlfriend is cool with you having sex behind her back then sure, but if not, tell one to be cool and leave you alone
