I feel like I am forcing myself to be straight???

I identify as a lesbian, and I am pretty confident in my sexuality remind you that I am a type of person who has to know everything if there's a question in my head I have to know the answer and I know we shouldn't put lable on ourself and let ourselfs explore things but what is happening to me is, I know I like girls and I don't like men in that way but for sometime ever since people have been telling me that it's okay to explore or it's just a phase, or it's fine it happens, I have this voice in my head mostly all the time looking at every single men older, , teenager, adult doesn't matter and I look at every single of them and ask myself do I like them and the answer is always no but I can't stop doing that because I can't answer myself how do I like women but not men because liking men should be normal and that's how everybody is, is there something wrong with me am I going to end up liking men because I'm forcing myself so much, what if I end up hating women with my overthinking but I love womens, as if I am afraid to like men or trying to stop myself from liking men but in fact I'm not but in my head I am, but with women it's easy I don't have to put effort to like them it comes naturally and during my teenage years( I'm still 19 btw), I've only had girlfriends never a boyfriend and yes I've kissed boys when I was like Very young but ever since I got self aware I knew I only feel attracted to women but after watching other girls so in love with boys, I don't understand how did I end up being a lesbian like how is it possible, is it gens, is it being too sporty or too much workout, I don't know I'm very confused it is practically killing my brain please help me, I'm sorry if I wasn't able to explain what I'm trying to say properly but I tried my best with how much I've figured out.... No offense to men out there I'm just very stressed at this point by all this mess in my head!!!! And I don't have any energy to date or be in a relationship with a men right now if you guys are you to say you should try being with a boy then see, even though I won't even think once if a girl ask me out though... Sorry
