Most homosexuals have a period in which they try really hard to be heterosexual. There are two distinct kinds of bisexuals. Parallel bisexuals can have sex with males or females at any time. Serial bisexuals can have a relationship with a man and then a woman and then a man and are the most common. Just because you have experimented with sex with the same sex doesn't make you bisexual.
Many porn stars engage in bisexual behavior but they do it for the money.
Then they go home to their heterosexual relationships. Most animals show bisexual behavior but sometimes the sexual behavior isn't really about sex. It might be for dominance. Having a growing bisexual interest might just mean that you are curious. Only time will tell what it is about.
