Sexual question

I want to know your views

If a man had sex activity with another man If he watched gay pornography has used gay dating sites one night stands with men. Had been in a relationship with a man for years, still checks out flirts guys.

Does that make him capable of being with a woman?

If he's bisexual likes both genders will he be okay or will he long to have more? Would he be content with a woman? What makes a man want seek other sexual partners?
