Does sexually experimenting with a friend of the same sex make you homo-sexual?

This is actually a serious question. My friend is a bigger girl, she wears like a DDD bra. She's obsessed with my A-cup. She'll poke at them, run her finger across my nipples, and comment about how cute they are. A few days ago she actually started sucking them. Call me weird, but I kinda liked it. I feel like such a dork for asking this because I'm 20 but would you take of the situation?
No rude answers plz!

Well having HOOHAA with a person of the same gender means gay or lesbian sex.
