LESBI HONEST

Who here has had lesbian interactions but isn't really a lesbian? 
When my friend was living with my we were laying in bed and talking and she told me she wanted to try some things with a girl (me) but she didn't know how I'd take it. So long story short we ended up having sex that night. 
No awkwardness after, it was a one night thing and that's all.
I am attracted to females and I like having sex with them but I don't want to date one. 
I have a boyfriend I've been with for over a year as love him more than life. 
Has anyone else had any similar experiences?
