Once you get into this I/R lifestyle you should talk and discuss these issues with your spouse. Talk about what each like about the lifestyle, whats ok and not, some ideas kissing, bare backing, who to be with let your imagination run wild when talking about this, you will have the best sex after. But make sure to discuss the what if scenarios or what we called the Oooop factor cause eventually once she gets serious into the lifestyle the talk will turn to it. As for us it is a turn on thinking about it, I would love to see her belly swell and have her walk around with a t-shirt saying Chocolate bun in the oven LOL yes its out there. But in realty as an older couple 40/48 with our ******* old and out of the house we like our lifestyle the way it is. But if she decides its time for it or the Oooops does happen she will let me know then.
