I'm confused I don't know whether I'm a lesbian or bi

I would date guys but I just would jump from one to the other, I'd move on so quick. I'd avoid having sex with them, I've never liked sex with guys, and I find penises gross.

I've find guys attractive but I don't think I could even date a guy again. I've dated so many guys could it even be possible to be a lesbian.

The first time I got with a girl, I didn't move on straight away I tried and it didn't happen
