"Experimenting" does not make you gay, or even bi. It just makes you well...curious? Lots of men and women have experiences with other men and women when they are young and horny and figuring themselves out. Don't be ashamed or worried you're turning gay its really no big deal at all.
You'll know in time if you're attracted to men or women, both sexually and emotionally. In the end you have to decide whether you'd rather spend your life with a woman or a man. Sex, personality, stereotypes, and emotional aspects all involved. Don't go with a woman just because she has a pussy, but don't go with a man just because he understands what it feels like to have a cock. Look for the whole package! In the meantime, if you feel like...experiment more.
