So my wife and I met this couple and got to know them quite well. After discussing all the formalities about the sexual aspect we played with them once. Later on after meeting them again for a few more times it was agreed by all parties that playing no longer had to be a couple on couple thing. We each hooked up with our new friends significant others for a solo occasion. The next day when my husband returned he had a look of pure fear on his face and began to re-live his experiences of the preceeding night. He stated that after having sex with the other woman she asked him what he would do if she got pregnant by him! This undoubtedly shocked him. He asked why and to his further astonishment found that she was no longer on birth control and failed to tell him nor for the matter her husband. He was freaking out at this point. Now we know that BC is not 100% effective and that having unprotected sex runs the risk of not only STD's but also a small chance of unwanted pregnancy, but I am terrified to think that this woman made a drastic life change without telling any party involved. To further the matter more it seemed not to bother her with the possibility of a pregnancy happening from my husbands sperm. Is this shit normal? Are there a lot of us in this lifestyle that are not on any type of BC and fail to mention or don't think that mentioning this might be important? Good god I hope not for the sake of many potential babies coming from fucked up matters like this.
