Need Advice about Boyfriend's Fantasy

[clare33]

Hello,
My boyfriend and I have been together for almost three years. We have a great relationship, and most importantly are true friends and respect each other. We have an amazing sex life (which I attribute to open communication and a respect for eachother). However, my boyfriend has one fantasy that is getting to be a bit much:
I have a sister that is a few years younger than me. She is very attractive. My boyfriend tells me how he has a fantasy about having sex with her while I'm in the room. At first, I just kind of laughed it off as a typical male fantasy. But sometimes it's getting to be a bit much. I don't mind him having this fantasy at all, but sometimes I think he wants it in reality a bit too much. We are very open together sexually, and I never want to make him feel bad about something he's shared with me. Has anyone else in a long-term relationship dealt with anything like this?

Clare sharing your bf with anyone can be scary because you worry that he might prefer her to you. This can happen so your fears are not unfounded. The fact that you feel this way, indicates that you feel insecure in your relationship - meaning there is a deeper issue here.

Your choices are:
1. to explain that you are worried and want to explore why - with him
2. try a FMF with him, you, someone else (not your sister)
3. do this FMF with them
4. say no to the entire scenario

I suggest starting with Option 1.

It's quite normal to have fantasies. It's when you start to act on makeing them reality that things get out of hand. The fact that he took the step of verbalizing this to you (and repeating it) leads me to believe he wants it to come true. EEK gives some interesting options and I agree #1 sounds like the best plan. Not to sound like a prude but most women I know would have smacked him upside his head when he said it the first time!

Why did she post this twice?

It's definitely a common male fantasy ... I would have it too if my wife's sister wasn't so damn annoying .... anyway, if it starts to seem too real when he talks about it, make it clear to him that neither you nor your sister would ever be up to that ... sometimes all a fantasy needs is a dose of reality ...

My wife has made it clear to me that she is up for any on the fantasy ideas that I suggest, as long as it only includes us .. all others in the room must be imaginary.

First, am I the only one that finds that gross? A fantasy is fine to have, maybe even ok to carry some of them out, but it's her sister. Who would be ok with that. He's saying I'm boinking your sister look at me. It seems kinda incestuous does it not? While she can't do anyting to stop him from having this fantasy, she can set boundaries on how they are carried out and her sister should be one of them.

No disrespect to this thread but here goes anyway...Anyone know what "Rodeo Sex" is? Well, ya mount up doggy style, get ahold of her shoulders and whisper in her ear that her sister is better in bed. Then see how long you can hang on!

Sorry for that, couldn't help myself I'll go to my room now
