Confused

So here it goes this is first time really admitting this all out. I guess for a while now I've questioned if I was 100% straight. I'm attracted to guys, I want to date them and do nasty shit with them butttt I feel and have felt I guess for a bit that I would like to have sex with girls too. I don't know really if I would want to date a girl but do things with them I do. If that makes sense? I remember when I was a kid thinking about being gay (I only knew about gay and straight then) and I was lile no I can't be because I like men. Even now gay or bi doesn't seem like the right label I guess to brand myself but neither does straight. When I watch porn I do prefer most of the time lesbian or like threesome with two girls. I've never seen a girl and been like damn I would do her but I don't know. I'm just so confused. Ever since I've moved away for university it's like I'm being more honest with myself but at the same time I feel guilty and wrong for thinking about the same sex. (I have tinder and I've been considering putting women and men)
