My girlfriend (34F) and I (33M) have been together for 1 year. It’s been great, we love one another, and though we always said we were open we lived essentially monogamous, with me as her Dom and her as my Sub. Now, we have decided to actually open up. I’m struggling with this because I think this is turning into something I did not quite anticipate and we had different ideas of what this might be like from the start, but never understood that. I have no reservations about “lending her out” for sex and other more casual and standard sexual activities with FWBs or even just acquaintances, but she desires to sub for very close/best friend doms whom she sees more than me given that we do not live in the same city. This aspect is not quite what I had anticipated and is MUCH more difficult to support and is much more uncomfortable for me because bdsm and domming her is so intimate and personal to me, and is an important part of our relationship. It feels special to me and so I’m more reluctant to support other doms doing it with her. The psychological aspects set it apart from more standard sexual experiences to me. Does anyone have any advice on how to become more comfortable with someone else domming your partner/sub who you love? Any input into my concern about how these activities can lead to unintended emotional connections? I don’t want to restrict her and want her to be happy but I feel like only agreeing to her doing more standard sexual activities with other people. I’ve not “branched out” myself yet as she was the first to suggest it, but she supports it and I suppose i will soon try this myself to see how I feel on the opposite side. Thank you to anyone with similar experience!
