I have always done OW - I started off in Australia 10 years ago, and at the time very few girls did OWO. However, after a 7 year break and returning back to the UK, things seem to be the opposite way round.
I do a mix of agency and indie work, and while I find that indie bookings are fine as guys can see this on my profile, I seem to be losing loads of agency bookings. The agency ask me to ring the guy who is thinking of booking me for a quick chat, and most of the time they will directly ask if I do OWO. I'm always honest, but as soon as I hear them ask this question, I know there is a good chance I have already lost the booking. I tell them that I use very thin condoms for OW and that it will make the experience last a bit longer, but I'm annoyed that the agency don"t tell them this before they pass a potential booking on to me.
I would hate to cave in to doing OWO as I don't fancy the (admittedly small) chance of getting the clap in the back of my throat, and I can't stand the taste of pre-cum, and some guys seem to produce loads of it. Would it be dishonest to say I offer it at my discretion and then try and get out of it i.e. bleeding gums excuse, or 'suck it and see' and hope that work picks up whilst sticking to my guns? I suspect I'd be a lot busier giving OWO, but being new after such a long break can take a while to get established again. Also, I say I offer a GFE, do guys automatically assume that OWO is included in this service?
