Well, YOU don't get to have a "hotwife" "your way". It's about HER and what SHE WANTS and it's way easier for her to just say no than it is to put up with your rules, wants and desires at that moment. I know I'm being blunt here, but I imagine there are several wives on here and even husbands who can confirm this. It will eventually progress to that, but the most positive step you can take is to encourage her to explore on her own and then gradually work your way into MFM. It's way easier for her to find a guy than for both of you to find a guy. It's also way easier for her to start her sexual infidelity with another guy than it is to try to please you during a threesome as a "first experience". Husbands ruin the experience quite often and the one sure way to get her to NEVER want to these things again is to make her feel uncomfortable with rules and suggestions for things she doesn't want at that moment. I've been in PLENTY of MFM's and I have seen it often. Best of luck though.
Join a REPUTABLE lifestyle site, put together a nice profile and some pics, and see what happens. Tell her it would be fun to put a profile together just to "see who is interested" , etc. That way she's on board with the whole thing. It might be fun for her and she may become interested when she finds out it's no big deal and that there are plenty of couples or guys who are interested and hot enough.
Mrs Hotwife.
