Sex with my best friend?!
well first off im 19, and a girl. i have been dateing my bf for like almost a year now and i do believe i love him a ton. but about a week ago i spent the night at my best friends house and i know i am bisexual and all but she is like my sister!! so anyway we kind of had sex and i liked it... so what do i do now? i can't just act like nothing happened should i tell my bf? or just keep it to myself and forget it?
