I like DATY. It's a bit hard for me to admit, because I'm generally a clean, safe sex kind of guy, but I really enjoy using my tongue on her tongue, pussy and even ass. This is very dangerous, I think because these are all exposed mucus membranes and therefore easier to transmit disease. But so far so good.
I'm glad I came across this thread because I've had a bunch of thoughts that have crossed my mind on DATY.
I like DATY because it can be a way for me to get the WG to show desire. Some girls will do whatever you want, but oftentimes I am skeptical if she's really into it. I know more than likely she's not. This is a time-limited paid interaction, after all.
Still, I want a full-throated reaction, which can be a tough demand. Some of the better WGs will act it out, but sometimes it's done badly and then I feel like a dupe. The opposite is also possible, sometimes I do turn her on, but she's the type to react quietly.
When I do my job right with DATY though, it's almost a sure signal that I've turned her on, because I can tell she's wet and she uses no lube. Oftentimes, I can also tell from the smell. It's not a delectable smell on principle, but I've learned over time what it means (that her juices are flowing) and that makes it very intoxicating.
It's also a turn on to see a woman want me, or at least my tongue, is small, subtle ways, to have her move her hips in search of my tongue, to have her fingers brush the hairs on my head and pull my face in close. I've had experiences where I know she's not complimenting me because when I reach up to fondle her breasts, she slightly risks offense by batting my hands away. She's just concentrating on her own pleasure.
In my experience, most WGs have been thrilled when I've offered to give DATY. It might be that it's rare, but it could also be just that they can avoid pounding for a little longer.
In one of my recent encounters, a WG yelped in pain when I went at DATY with far too much vigor. In more recent encounters, I've been far slower and delicate, and it seems to be appreciated. I may have been doing the DATY equivalent of jackhammering in the past.
It's harder to get the delicate touch right, though. My instinct has been to match the way I put my mouth to her delicates with the way she puts her mouth to mine, but now I'm thinking I have to be a lot more gentle.
It's tricky, because she's done the sexual equivalent of breakdancing for me, and here I'm trying to do a delicate waltz for her.
One other thing, after being with WGs and trying to learn from them: A lot of girls I've been with (not necessarily in MTL) don't swallow. As you might expect, you tend to pool up a lot of saliva when your mouth is open for so long -- think about what happens when you're at the dentist! A lot of WGs take that pooled saliva and spit it into a nearby napkin. I guess that's for health reasons... if you swallow it, some of it can infect your throat. I haven't learned to not swallow yet.
