is it ok to be lesbian?

i think i may be lesbian because i found this girl at events and adventures and we were just going to be really good friends and will i feel in love with her and she fell in love with me she said that form the time we were first friends.and i was a little scared to say i was lesbian and wanted to go out with her and she was like can we go and talk some were by or self and just learn a little bit bout each other and so we could not find a place to just talk will we ended up going in to the rest room and she said i gotta got to the rest room when we walked in and i was like cool go and then we can talk she said no i want you in the stall with me and by that time i was turned on by what she said i thought ya shes lesbian so i asked her if i can watch her go to the restroom Caz she said don't look Caz she don't like other women watching her go to the restroom. and she said yes so i turned around and watched her go.will after she was done we kissed a little bit and talked when we wont kissing. and she has said to me that know one never came in to the stall with her be for because she was ugly and changed her mind about dating her.she was also a little scared that i would say know and was gonna heat her like every other girl she was gonna do it with so she had to think if she wanted me or not but she was like i asked to watch her go so she was pretty safe to say its safe but then we took our clothes off one each every 10 minutes till we got done too nothing was on any more so we ended getting engaged after about a year of dating and about ounce a week we would do sex with each other but every night we went some were. and im 23 and she is 22 is it ok to marry her in a weeek or so from today or is that a little fast
