Could I possibly be a lesbian?

First and foremost I'm a 26 year old woman so I'm not going through a phase.My first sexual experience with a female was at 13.Years later as an adult I found myself having casual sex with other women.I also was in serious relationships with two different women.I would have dated about three other women but lets just say they weren't for me so I decided not to go further with them.I find women more attractive than men.I'm currently in a relationship with a man which is alright but I find being with a woman is more comfortable and better.I'm very feminine and I doubt anyone would suspect this of me.But it's just something about a woman you know? It's not just a lust thing honestly.If my boyfriend and I were to depart I honestly would seek women only.I would like to be in a long term relationship with a woman.I like the masculine type of women to date,the studs.Though I've had sex with the feminine type as myself my preference are the masculine types.
