I think I want to hang out with other girls.
Why do you want to hang out with other girls?
I want to loose my virginity to both a girl and a guy, because I've always been curious about this
While it is your choice who you want to have sex with, it is not good to cheat on your girlfriend so that you can have a threesome. It will be hurting her.
Just a friendly time together in bed, not a big deal. I am going to look for a guy I think.
I really think you should talk to your girlfriend about this first before you go ahead with your plan.
