I'm thinking of leading two guys on
Why would you lead on two guys?
I just want to have fun.
It is okay to date others.  But, it isn't nice to lead someone on just to do it.
Uh, I'm starting to feel bad.
You should feel bad. Leading two guys on with no intention of dating either is just mean and they'll feel used and dejected. Have you thought about how it may feel if you were interested in someone and they pretended to be too?
