You ladies are all wonderful and enjoyable and DATY is one of the best things I enjoy about the hobby, especially since I can't get DATY at home. Sensitivity, clitoris size, g-spot stimulation, its all good but varies significantly (probably like us clients). But, especially when we are with you the first time, positive feedback, especially verbal is what we need. The one thing I've learned is that if something seems to be working, keep doing it.
One other thing; I almost always shave my face right before a session. I'm not particularly hairy, but I do not want to cause your thighs and sensitive parts to get beard burn. The one time recently that it had been 4 hours since I had shaved, I was asked to slow it down because of slight stubble from my chin! Also, most ladies like my mustache, which is thick enough to be soft. But, the same is true in reciprocal. I have had significant lip and chin irritation (sometimes lasting for days) from pubic stubble. I do plan to spend a fair amount of time down there, would appreciate it if it were properly and recently shaved. Either that or go full bush, which is nice and soft and altogether different and nice in its own way.
Being a southern gentleman, I usually try to follow the "Ladies First" rule, especially the first time we are together. Usually makes the rest of the session much better.
Finally, in between sessions, I do exercises to keep my mouth open and my tongue out and stroking for at least 30 minutes at a time. Helps me be prepared in case it takes a while for my partner to get going, which sometimes happens.
As Jeff Foxworthy says, ladies are like a diesel engine. Sometimes they are hard to crank up, but once you do, they can keep running forever. That's the part I love about all of you.
