LESBIANSSSSSSS ... except I have a boyfriend...

I'm bi, and my boyfriend knows this, but I actually haven't ever experimented with a girl. It's kinda weird because usually I don't really care, but once in a while, I will just get huge sexual urges for girls (no one in particular, just experimentation) and it scares me because I love my boyfriend and I don't want him to get insecure or think I'm thinking about girls when I'm having sex with him. Idk it's just scary because for the last four or five nights in a row, I have had at least one wet dream with girls per night.
