The jealousy will not be experienced until, and unless, you see him enjoying another woman.

If you read many of threads on threesomes, you will find that there appears to be eagerness leading up to it but big letdowns following the actual experience.

You two started together at 17. Perhaps this is just either or both of you feeling you have missed out on experiences with other people. Talk it through thoroughly.

Your dating another woman is entirely up to what you are comfortable with and what the two of you have negotiated for your relationship.

Please get over this idea that in an FMF "same-sex" sex must automatically occur. It doesn't. Same with an MFM - which is actually easier to set up. You won't know if you're jealous until it happens and then it will be too late.

Wihile FMF is a major male fantasy - he thinks the women will be all over him - few realise that he's now got double the work to do but he still has that refractory period. It can be done but it does take upgraded skill.

Younger males see a guy in bed with more than a few women and think great! A more experienced man sees the same picture and thinks "I'm dead".
Why? Because in failing to satisfy the remaining women, they will tear him apart.

Men are muskets; Women are Gatling guns.

> I can get jealous some what easy so I was wondering would it be ok for me to be with a woman and see if I like it

My recommendation is to wait and not do this until....

You have to ask yourself why you become jealous easily. The two of you need to have a frank, thorough, discussion regarding expectations, actions, and especially boundaries for all concerned. In other words, make rules and implement them.

Do you know what being jealous is all about?
* First, the behavior has to do with being insecure
* Second, the behavior has to do with having a lack of trust in the other person
* Third, becoming jealous often manifests itself with becoming fearful of "what if's":
- what if my boyfriend likes what she does better than what I do?
- what if this third person likes my boyfriend, will she steal him?
- what if my boyfriend appears to get turned on more by her than me?
- what if...
- what if...
- what if... (fill in the blanks)

Unless and until you can come to terms with your own feelings of insecurity by developing trust in your partner as well as yourself, then you are setting yourselves up for a "train wreck" looking for a place to happen.

For a threesome to work, it is necessary to take the emotional component out of the equation and simply have sex for sex sake. If you cannot do this or trust your fiance to do this, then the answer is no--do not do this.

No, it makes you none of those things. I have never been involved in a threesome and the closest I have come to group sex is when two couples of us would travel together and, to economize, would get a room with two double beds. Why have I not tried it? I do not know. Simply never came up in a context that I considered inviting. That does not make me a prude and it does not mean I disapprove. You are open minded enough to entertain the thought and, likely, will act on it if the situation is correct. The jealousy is your choice and your choice of words.

Actually no, taking the love out of sex frees the sex to be what it is - pure pleasure - fun for fun's sake. You don't need "an agenda" to have fun, do you?

And yes, I've ad more threesomes, foursomes, and moresomes than you've had hot dinners. None of them involved any "same-sex" sex.
