I think that going to a social or dance while pregnant would be ok (pregnant women need to get out and have fun too), I would go just to hang out with my swinger friends and get all hot and bothered, but James is that only one I would be doing anything sexual with until after the birth for 2 reasons - 1. I wouldnt play with anyone, male or female, the STD risk is just too high - and I know that you want to have a healthy and happy baby. 2. In the grand scheme of things, nine months is NOT such a long time to refrain from swinging. This is such a special and sacred time for the two of you - bringing a child that you have created together in to the world - make this time about the both of you.
Have a great time at the social - dancing is really good excerise for pregnant mommies
