In my heart of hearts I know I am a lesbian and it feels right. However I still question it. Sometimes I think that its me having a problem letting go of the idea of a hetero lifestyle and other times it's that I might possible be Bi. I don't feel I'm bisexual and I don't just want to use bisexuality as some sort of gay acceptance stepping stone, I want to know for sure. I don't know. Is it me still trying to accept I'm gay? or is there more to my sexuality? Its really frustrating and I think about it often. Plus this sort of questioning is actually what's keeping me in the closet and guys its pretty lonely up in here.
That sounds like me a few months ago. I first identified as bi, since it was the easiest and that I wouldn't miss out on anything or be awkward if I realised I were attracted to guys (I really wasn't... But I weren't sure). But I didn't like it that way, I never felt at peace with it and I thought about it soo much. Then I started identifying as lesbian, it felt way better but I still had some insecurities, but no they're almost all he way gone and I don't question it often at all, only when I realise it's probably gonna be a problem when traveling and stuff, if the world haven't changed by then. I'd say, start to identify as a lesbian, and if it's right, I think your doubts will disappear with time. The best to you!
