Cleanliness first!

I absolutely love giving and receiving. Clients tend to like it during BJs, but I always ask first for the aforementioned reasons. Clients know I keep my body super clean for dates, and it's an expectation I have of them as well. So that would be my highest recommendation: clean down there (a quick finger in the shower with soap helps) and your mouth before engaging. That way, both parties feel uninhibited and eager to explore.  

Also, no double-dipping. If one's finger has been elsewhere (especially in my womanly crevice), it must be sterilized first. Or use a glove. This helps to keep everyone safe in terms of bacteria/disease.

I really love to use all my appendages when down there: breath, tongue, lips, fingers, even small nibbles with my teeth. It also encourages my clients to feel comfortable exploring on me too. It's a great way to build intimacy and excitement, which always leads to more dates

I'll usually on DATO with someone who is freshly prepared to have anal sex. That means very, very clean. If I venture there otherwise, I avoid the area at the slightest detection of ... use your imagination. ..  

Also, as is the case with anal sex, my partner has to enjoy the attention. I'm not just doing it for me. No pleasure, no dining

I had some rimming done on me for the first time recently.  While it felt good, it wasn't mind blowing or anything.  Given the limited time and the greater pleasure in other activities, it is not something I will ask for or miss if it never happens again.

It's not something I ever plan on doing, but occasionally, usually while DATY  it seems natural to explore further, particularly if I sense that the Lady is really into it.

hygiene is at most importance...

as i mentioned before, i am not gonna apologize for my desires and likes

Two of my very favorite playmates (one a professional, one a friend with benefits) loved to climax with me performing DATO. One used a vibrator, one amused herself by playing with my anus testicles, penis and causing me to squirm; the moreI squirmed, the harder I worked at my end and the more excited she got.  In general I find well review DATO only second to well received DATY.
I have had Hep A from eating oysters at the source of the best oysters in Europe but the bay must have been contaminated because there was a small epidemic.
I have been vaccinated for Hep B. (And, by the way am up to date for polio which can be transmitted by the O to mouth route.)  
I agree cleanliness is paramount. There are other things that make it wonderful for me, but the key for me is the effect of my action on the recipient.

I am a fan of giving provided my lady enjoys this intimate act and of course is very Clean!
I think it is one of the most intimate sexual acts to work your way there and tenderly caress her with my tongue.

It should be included in everyone's menu. DATO forever lol

Every provider has been willing to let me go there. As long as the woman is clean, then I am willing to give her a great rim job. So far it has been no problems with any ill effects. I am hoping my next provider will let me be more adventurous in the area, and use fingers as well. I like the way a provider reacts to my kissing and licking of her back door, makes me feel good that I am giving her some special pleasure, and I feel like a rebel because I am doing something out of the normal that people do feel is disgusting and unsafe.

Make love to it with your mouth lick it don't stick your tongue INSIDE

I am cool with whatever to me, but it then limits some other things like kissing after.  Even though I am very prepped for sessions, it is still a rectum, folks.  I have rarely had an encounter with a man who wants ass play who is as consistently clean as I am.  There have been some amazing exceptions...so if this is your thing, by all means clean up.  

And yes, I do not prefer double dipping...have had it happen, but it really is not prudent. lovig this community for her health consciousness despite very playful spirit!
