I Think I Want To Lose My Virginity To A Fellow Woman

I am a virgin. I masturbate and watch porn and stuff so I’m not unaware, but I previously chickened out of sleeping with men that had obviously been wanting to go down that route. I’m still working on why that is lol. But the thing is.. I’m like 98% sure I’m straight. I like how cocks look and I like men and have always only liked men. Though when my girl friends and I sit on each others laps or full on body cuddle, I get a tingly feeling down there. I do know that I feel sexually attracted to women’s bodies.. but I have never emotionally liked women even close to how I’ve emotionally liked men. At this point I don’t think it’s right to call myself a bisexual if it’s solely physical attraction. I grew up freely changing in women’s locker rooms, in front of friends etc.. so I’m inherently more comfortable around women. It’s normal for the women around me to slap each other’s asses or playfully grope one another, it was done to me and I had done it back to those same friends. Rubbing pusses and giving each head sounds less scary for my “first” time. If I want to follow through with that idea… should I download a dating app and specifically say I’m straight and just want my first sex experience to be with a woman? I would ask my friends but they are all straight and have boyfriends. Or should I just not? I really don’t want to intrude in the lesbian spaces but I really think It’d ease me into being more intimate with other people instead of just my toys.
