The last two Asian providers I have been with (neither reviewed) have allowed my uncovered penis to be all over their genitals.  It wasn't until penetration that a cover was put on.

This of course brings up a number of health and safety questions.
I'm well aware of the dangers but that's not the issue.

Is this uncovered genital to genital contact commonplace?  They're the only two providers who have done that with me and both were straddling over me when they did it.

Not from what I am aware of. To me, uncovered genital to genital contact is risky and unsafe- whether penetration occurs or not, the risks are the same, and it is not worth it. From my understanding, such contact is quite uncommon and avoided by most professional providers. I am unsure if the race or ethnicity of the provider has anything to do with it- I am a Caucasion/American provider, but from what I know this is not common practice in the hobby regardless of any other factors.

I like my body too much to put myself at such risk, and I think most ladies would agree.

On the other hand, I love the visual and sensation of genital to genital contact- but a cover is essential.

are more common than people will admit-

have had three reputable providers do this-  by in large they avoided heavy contact with the tip, but there was certainly shaft to clit contact.

It is risky business.

Without exchange of fluids, sliding her genitals against the shaft of your penis is no more dangerous than BBBJ or DATY as far as the risk on contracting STD's.
Penetration of course is another matter...

Agree with muchmoretoit.  there's a lot more going on out there than anyone will admit to on these boards.

Mostly true Boston- except perhaps for herpes and genital warts-

neither transmit as well genital to oral or vice versa as they do in direct contact.

Nevertheless-  didn't say I didn't allow them to do it!  Felt great, but did register a little concern.  They are careful providers in all other aspects as far as cover, screening, self testing, etc, but sooner or later you number comes up!

The second time it happened I had just finished DATY.  As she was grinding away, I remember thinking to myself that this was probably not a good idea, but no more riskier than what I had just finished doing.  So I let it continue.  

The real danger is if you are both enjoying it too much and your uncovered contact is that close, well, we all know what could happen next.....

Of course, Herpes, when not in outbreak mode, is tough to detect but if I see genital warts I'm not going anywhere near the lady anyway...Thank heavens for ATF's!

I've played with oil before but never genital to genital action... I mean the hobby is pretty risky as is... Why take more chances..?
