My spouse and I are interested in adding threesomes into our sex life. Both MMF and MFF. We are super cautious about STDs, and both took tests prior to us even engaging in sex. In the BDSM, non-monogamy, or poly lifestyle, how normal is it for STD tests to be done? Would that be too out of the box to ask for, or do you find that most want exclusivity with the group due to the potential of STDs? We aren’t looking for exclusivity, just looking for long-term options, or partners. We just want to put feelers out there to see what common practice is.
