I think if you sexually fantasized about girls there is definitely something there to explore. Have you talked to your boyfriend about bringing a girl in to the bedroom? Are you ready to see another girl sexually with your boyfriend?
You can't be with your friend and hide it from your boyfriend. Usually in a group of friends things get out and you could end up destroying your relationship with your boyfriend.
Talk to your boyfriend and ask him what he thinks after all, you are in a committed relationship with him. I don't think he would be happy you went to a girl on your own.

I hope this helps

i agree with blindedbyblonde, i'm in the same situation as you, and i'm stuck to fantasizing, i've been with girls before but i would never be with a friend, it would ruin the friendship (trust me i've tried it) not that a stranger was any better, she ended up stalking me and threatening to kill me so i'm scared to go near girls that way now, if you don't want to involve a girl sexually with your boyfriend then perhaps tell him he can watch (if you're comfortable of course)

best of luck

Stranger. Always a stranger. You may be more comfortable with a friend but you also stand to lose a lot more if things go wrong.

I say stick to a stranger...craigslist, be careful and take your time..meet them for drinks..and find a hotel..that way you cannot be stalked..Irasistabelle and I know that all too well

I would actually say a friend, unless you are worried about discretion (ie. want to keep it a secret). When I started feeling the way you did a friend told me she was bisexual and made it completely comfortable for me to start talking about it. I've ended up hooking up with three friends (separately, I'm not that much of a pimp:) ) and have always felt safe. Your boyfriend being involved may make you more comfortable, but bear in mind that the majority (but not all) of threesomes in a relationship end up damaging the relationship with jealousy or even further attraction to other people. Good luck and enjoy.

I'm not sure that many women/girls are 100% straight (although many would challenge this view) and I think this has evolved over us being more tactile than men. In any situation though, stranger sex, be it with a man or a woman is never the best.

If you have a willing and considerate friend I think this would be your best starting point. However, I would suggest you don't involve your boyfriend at all. I think this would be taking on far too many new experiences at once and potentially ruin the intimacy and the softness of the situation.

It would be nice to hear how you get on.

Some secrets are best kept that way no matter how open and honest you are with people you love. I am choosing to not tell my new boyfriend that I'm curious about women, but the secret is driving me crazy. I can't imagine hooking up with a female friend. Sex always changes everything. I've had sex with three of my guy friends, and it always got awkward after that. I just wanted to have fun. They wanted more. With a girl, I'd be afraid that I fall more in love with her than the guy I'm already dating. In this sense, I want to say do it with a stranger, but it will be unfamiliar, risky, emotionless, and nerve-wracking (unless that's what you want). If I had to choose one, overall I'd say do it with a friend. At least there's already that open channel of communication/trust, and from what I've seen, unless one of you falls in love or gets possessive, women can stay good friends after hooking up. It should be made clear early on, though, where you both want it to go... if anywhere.

i am in the same boat. the best thing to do is be honest with your boyfriend and let him know your feelings. i promise he'll be more hurt if you try to hide your feelings. i wouldn't recommend craigslist, since it has gone horrible wrong for me in the past. but i do agree with blindedbyblonde that meeting a stranger for drinks first is the way to go. things just become more complicated with friends
