In the strictest definition, it means you're bisexual. আপনি don't have to like guys 50% and girls 50% to be bisexual. আপনি can have a 10-90, 20-80, etc. ratio and still be considered bisexual.
But it's up to আপনি how আপনি want to define yourself. If আপনি identify yourself better as a lesbian, then go for it!
