Great discussion topic! Here's been my experience with facials.
I have kept my own "historical records" of this. I have had sex with 68 women; 48 of them took a load in the face. I've pretty much found that there have been no trends in terms of less women in the 00's taking them than in the '20s, for instance. 20 of them have let me video the facial.
I've strongly suspected that a lot of women have told me they've never taken a facial before me are lying about it; but really that's what I would get for asking. It's hard to describe how you can tell if they've taken a facial; it's just a sixth sense. But a couple of them have been good about assuming the position on their knees, and positioning their head pretty accurately for their face takes the the shots. I would think most newbies would be too timid for that. I honestly get super turned on if the woman is like, "Yeah, I've taken a fair/good amount of facials before". But women tend to be pretty coy about it for the most part. On the one hand, it really is none of my business if they have if they aren't comfortable telling me; on the other hand if it really is your first time, it's good to know to help you through it and be more communicative so you can be more comfortable.
I haven't found a pattern in my experience one way or another of women who are enthusiastic about facials being the ones that end the relationship/FWB. I have found that if you want to give her facials, you better come correct with something else they want. Some of them, just eating their pussy out a lot will make them open to it, it just depends on the individual. You just need to be prepared to work for it and give them their equivalent of a facial.
I honestly feel pretty happy for the next guy if I got to train my recent ex to take a lot of facials. I like to think that she'll take thousands more. I just never truly know how many men ask for it, or how often women get asked it. Most women seem to be able to take it or leave it; and with a few of them, I can imagine they might have felt a sense of relief if the guy after me didn't ask to cum on their face. I think women like breaks from it.
At this point, I don't really have a hard time with women who take facials being in the "carrying a torch for" department. Facials have been frequent enough. Are my stats skewed? I never would have believed at age 20 that I would have had this high a ratio of women taking facials. I guess the law of averages would mean that ratio should go down in the future; so maybe I should carry torches.
At this point, the ones I carry torches for are women who eat ass deep and nasty. I'd say I've had somewhere between 12-15 women who give hardcore rimjobs. Although, the ass eating ladies have been coming out of the woodwork more over the last decade, in my experience. But damn, I just lose myself for those women.
I'm looking forward to more responses on this topic and hope this thread can take off. It's fun to read about, and I've always been curious.
