Mr occ here. Mrs occ likes group play. Couples but also gang bangs. I have found that once you really dive into group action touching other guys just happens due to proximity. Once I got over the initial "omg I'm touching another guy" thing, then it became a turn-on. So now, if everyone is comfortable with it, bi play just becomes part of the fun. Whether it's just touching or full on blowjobs or more. Just find your comfort level and then let go.
