DATY is up to you. If you don't like it.,,,,,don't DO IT.
I don't like getting pegged or prostate play. So I don't DO IT!.
What is there not to get???

I genuinely enjoy oral sex when guys know what they are doing or take direction well. I think the better question would be to ask yourself why you have no interest or no desire. I know gals that very much do not enjoy giving a BJ, but when asked it is usually because they had a very bad experience with a guy being very aggressive and shoving his dick down her throat or cumming in her mouth without asking permission first. Only a small percent of women can orgasm from penetration alone, so unless you are stimulating her clitoris with your tongue or a toy not very likely she is going to climax.

" I thoroughly enjoy giving a girl pleasure but not that way.". Why not?  What's the concern/issue?

As for a provider response, they run the gamut from don't want it to pretend to want it but cut it short to really like it (or truly a great actress).

I’m particular about it. It has to be shower fresh. I appreciate the girls who say hygiene is a big deal. It is to me also. I don’t like huge lips or huge clitoris so that’s a no go for me. You’re the consumer so do what you like.  

is better then to receive! I prefer to give DATY over a BJ. Rarely do I cum via BBBJ. But, to get round 2 started, a BBBJ does help this old guy get the engine turned over. If the lady really wants to give me head, I'm not gonna interfere! Only complaint I have is a 2-3 day stubble!! Getting "rug burns" around mouth and lips is a bitch!

You’re not paying to do something you’re not into. While escorts may enjoy it, if you’re a gentleman and treat her right, I’m sure she’s okay with you not doing daty.

for me  DATY is standard practice ..  it gets a woman much wetter and relaxes the vagina muscles so initial penetration is much easier.     i also find that if one can truly satisfy a woman that way first she is much more inclined to take extra effort to satisfy you,  that includes doing things she swears she never does   (i do not mean anal) so will leave that to your imagination.      

i have learned its very simple, the nicer you are to a woman, any woman, the nicer she will tend to be to you.    besides i can get myself off,  its a nice treat to enjoy and experience a woman's sensual pleasure.  

Why don't you ask for a discount pal, if you don't think you are getting your money's worth. .... See how it goes
