Is it ok to have 2 boyfriends?

Go ahead, but if you get caught then its not my fault

Can you? yes.

Should you? that depends on several things, including

how much you care about what other people will think of you

how much risk of STDs you're willing to take since if you are not being faithful to one guy you can be sure he's not being faithful to you. He'll simply see it as you accept that he's going to sleep around.

Other conciderations: are you talking about simply dating 2 different boys to find out which one you like? or seriously dating 2 different boys? If you're just not sure which one you like, there is nothing wrong with going on a few dates with each of them to determine which one would make you happy.
