Yes, same with us. Two from our group of friends and a few others from the non public club we belonged to.
From our group one mid thirties hetero woman, single (by choice) career woman who wanted a child selected and with all parties in agreement over the coarse of a month was pregnant (not at our gatherings, in private setting) semi anonymously. And the bi female of a lesbian couple (both would attend meet and greats and social events as a couple only) again they choose anonymously. From our club group similarly hetero couples and one lesbian couple (both attended but one bi would play with couples with bi female wife only). As far as I know all made their choices as to who and how. Of those I know personally it was never just one chosen male but several. None in a swing setting yet of those at the club the location was used for privacy (not their home, not a hotel) one on one but several over a time period. Just sex, finish inside. The selected males, one after the other and never identifying the “father”.
I have been asked a few times over my lifetime, twice before the lifestyle but have not participated. I’m just not that guy to father a child but walk away. I would need to be involve, it is who I am.
I am currently very close friend to a couple, both started thier lives hetero, husband, children, divorce, bad relationship experiences, entered the LS with a boyfriend, discovered their bi side, stayed in the LS after breakup, found each other, bonded, and now live as a full on lesbian lifestyle/couple but both are bi. I have been a good friend and FWB, lover to both over the years. We all do social things together, they as a couple and the Queen and I. They also from time to time one or the other visits for some intimate loving and social fun. The Queen told me there has been discussion of wanting to take me away, the both of them for a weekend away. Hhmmmm.
At the end of the day we are all human, we all want acceptance, to be appreciated, valued…etc. And for those you walk past every day they all have differing lifestyles, wants desires, dreams…..not just about sex…..not all of the same mold.
