Yes I have realistic idea about situation. So many people just treat it as fantasy/fetish but dont really look into how it could realistically be done. It happens more than people think. Celebrities are also well-known to use female surrogates and male "sperm donors". The ancients would have their Gladiators, slaves, soldiers, or warriors breed with their wives and raise it as their own. This is honestly not anything new.
Also many think it's taboo cause its a White couple raising a biracial Black baby and how they will be seen by friends/family. So the most intelligent solution with the one couple I worked with was that they had me donate my seed to local sperm bank. Even though the wife was seeking to get breeded the natural-cuckolding way by me, they had that as a cover but also a backup. The extra $500-$1000 fee you pay for sperm bank is worth headache down the road trying to explain to friends/family/community and any "repercussions" as you say, of a Black baby coming out your wife/gf. You have actual verification if others become suspicious (if thats a concern). Sperm banks are being used more these days, and its usually when male has hard time conceiving or doesnt want offspring for genetic reasons. Its not uncommon for a couple or woman to ask for sperm from another race for a multitude of reasons.
I feel like I do under any swinging/cuckold situation in that Im helping a marriage or relationship. Personally, I feel also feel a great primal instinct to spread my genes being an Alpha male. One couple it was a one-off thing. They were more secretative and told me "thanks" and seemed to be really happy, but never heard from them again. Another was different. as me and the hubby were like friends, but he couldnt have ******* after trying many years with his wife. We initially met when I posted ad in old Craigslist personals lol. After 2 seperate breeding sessions tried got pregnant but had ectopic pregnancy. We discussed trying again, but this was back in my home State and I had to move away to earn my Masters degree in another State. I still talked to both for awhile and talked with the wife longer because of social media. Now I hardly talk to them at all, probably because I hardly visit back at my old home State these days.
The lesbian couple was the most secretive. More than heterosexual couples, they definitely dont want the male breeder involved lol! At least from the experience I had with the one lesbian couple and the one I had sex with was technically "bisexual" she said.
So to answer your question, I havent been involved very much during the pregnancy for any of the couples and I dont mind that. I would never ******* custody rights or impose myself on a couple or family. I treat it as swinging situation of helping with sexual satisfaction for the woman and adoption type situation when it comes to breeding. Hopefully this answers your questions. I was actually about make a post in reference to this in General Discussion.
