How can I be sure that I'm bi?

I think I might be bi but im not sure I like the feeling of fingering my butt and then again I like jacking off to girls too but I dont know if im bi or not. can you help me please?

Its easy just if you like to touch or the look of other guys then you are bi if not then you are'nt. Just because you like fingering your butt does'nt mean your bi it means you need or want to have s*x.

well if you look at girls more than guys then you probably are bi. are you more into both boys and girls and not just one if so then you probably are. theres nothing wrong with being bi either im bi and noone feels different about me so give it a shot, if you don't like it then change back. what ever feels right to you folow your heart

An*l stimulation has nothing to do with sexual orientation.

Sexual orientation is about whom you are attracted to (males, females, or both). If you are attracted to both males and females, that would make you bisexual.

How and where you like to be stimulated is something completely different and unrelated. Many people enjoy an*l stimulation whether they are homosexual, heterosexual, or bisexual. Men often like an*l stimulation because it also stimulates their prostate.
