help! lesbian?

okay so i cant really explain this but basically i’ll think i’m a lesbian, and then ill meet some guy and i’ll want to date him, but every relationship/date i’ve been in with a guy ends up being awkward but am i just making it awkward? i tell them i’m a lesbian and it just repeats over again. please help 😩🙁

EDIT SORRY:

yeah i’ve been dating girls for a while and that’s why i think i might be lesbian but i really don’t know i just feel awkward about thinking about dating guys
