So you're married and yet have never had a blowjob?
If that is true (and it's a big if) then you're truly tragic
I've known a few women who wouldn't put their mouth near a cock. (And likewise, known a few men who wouldn't ever want to do RO.) One of my best friends when I was younger used to heave at the thought of sucking cock, she was soooo easy to wind up, I would just start talking about it and she would be practically throwing up
Sadly it looks like the OP managed to marry one of these ladies, and after the "I do" she still didn't change her mind.
As to the OP - yes, some women are happy for their husbands to go pay for it, it's not as complicated as an affair where feelings are (can be) involved, and one night stands can be emotionally messy, so paying for it means the husband can get to experience safe (hopefully!) sex and exploration while still being part of the family - emotionally, financially, physically etc etc. I wouldn't think most women would see it like this, however, you would need to have a pretty open-minded wife to begin with, and wives who don't want to give blow jobs tend not to be sexually liberated enough to cope with husband seeing prostitutes.
Hope your first punt goes successfully, BJVirgin
