I used to offer owo many years back.
Then a few years ago I decided to withdraw this service.
Like some girls, I was worried I would lose business and I have to say I did lose some of my regulars for whom this was a must, but to be honest, the ones I lost have been replaced by those that ONLY want oral with.............
Whenever I go to my usual sex worker's clinic for a check up, I am frequently told that there are many girls offering this service and not really wanting to at all but fear they will lose money if they do not. I have even heard it first hand from one lady I know who says she hates it but fears not offering it.
I hate to say this and no offence to anyone that does offer owo, but one thing I did notice, is that since not offering it, the quality of my clients has improved! I don't mean that in a detrimental way to anyone still doing this but for me, I think it was in some way a journey of progression from taking on rather more PSE bookings whereas now I am most definitely GFE and tend to prefer the less shall we say, energetic client!
The one thing that does get my back up is when guys ring me up, and knowing (as it's clearly stated on my site and profiles everywhere that I do not offer owo) that, still try to ask for it.......... some even say, oh won't you do it just for me.................

Some arrogant guy told me a few weeks back that all men want owo and didn't I know that? .................. I think I just hung up on him then.............

Saying all of that though, anything we offer is an individual choice. One thing I have learnt in this business is that you can't base your income/bookings/clients on what the next girl is doing because we are all different and offer a different type of persona...........
I am pretty sure that I do have some clients that come to see me that will still go to other's for owo but still come and see me because they like me and sometimes the basic services are neither here or there, if in fact, you have built up a good relationship with a regular client and build up a good client base of your own.
As for the bareback issue, no you cannot equate the two at all.
