Ha, I like how this thread started as a nothing burger, but it took a life of its own
Personally, swallow (SW, disambiguation) is not a requirement for me, but is it nice sometimes, yes. But it is personal, vibe based choice of the SP, I would never demand it. For ladies, including civies and SOs, it more of a i like you, you are mine, I want all of you. When it happens on occasion, even with SPs, I like a little boy say thank you, or you spoil me, and I truly mean it, because she appreciates me enough to do it, and I truly appreciate her, certainly not thinking it's some dom/demeaning act...
CIM is so much better, experience and sensation wise. But it all goes in the basket do you click, vibes, etc. I have many SP experiences, where even if she says no CIM, she does it for me, here and there, but i would certainly not demand, its more of if the mood strikes...
Since we are adding rimming and/or anal play, I love ladies who seem to have 4 hands and 24 digits, and it becomes a true oral cornucopia... and double, two way, 69 version. I love this more than CIM and SW, and when its along shaft, taint, BLS play, along HJ and finish, is absolutely better to me than requiring SW, or even intercourse, any day.
Not to be forgotten gents, and I'm on the side of SPs here, 1000%, absolute hygiene. To requote theredmilf, we should be using the word IMMACULATE not clean, prim and proper, etc. Like get in there, rub and scrub, rinse and repeat. I have walked away from SPs and civies less than perfect, and demand nothing less from myself.
Lastly, I think there is a 3rd aspect of SW, and it's the king, take a back seat, treatment. I more associate this with Asian girls, you get the full treatment along with a proper massage afterwards, so SW is kinda part of that, as in clean me up, and take care of me. Sometimes I just need that. And no, it's not a dom thing at all.
