The moderator whose name is The Love Goddess, is a professional counselor and may have some insight for you.
My thought is I dont think the fact you see yourself as a nice guy(sidebar: maybe you are in the eyes of the fair sex and maybe not) has anything to do with your recent results.
This kind of thing can happen though, to tell you the truth, its' not happened with me and I dont think Im an asshole around women. I sure hope not..I do have a lot of respect for the true professionals here as what they do is hard..just hard much of the time and that is not understood by most.
So is it an extended run of Good Luck?..I dunno..I think its my clever insightful selection process but maybe my turn is coming..I'll be frustrated if it does but, in any event, The Love Goddess should be able to give you a professional perspective which I think should be helpful.
Good Luck to you..oh any hints on which agencies you use? Just asking...lol

I'm still new to this hobby and I need help.  I have used one independant (great experiences but looking for something different) twice and I've used an agency three times.  Using the agency is great because I can use a credit card and they are easy and fun to work with.  That being said, I am one for three in good experiences.  One spectacular, the next so-so (she was there, but having trouble staying awake, not very erotic)and the last (yesterday) horrible (enough said).  This is an expensive hobby to go one for three.  I figured using this site would help get better results and the two bad ones had great reviews.  How do I keep getting girls on thier off days?  Although I am married I am not great with women, this is why I have to pay for it (LOL, not getting it at home, who does from thier wife?).  I've always been the nice guy.  Is that why I keep getting the shaft?  Should I try being an asshole (seems like the assholes always get the hot girls)?  I guess I'm just frustrated, I don't have the asshole gene (LOL).  I've stayed in a sexless marriage for 15 years, for love.  I finally caved and figured I'd go with escorts to get my desires met, not try and get into another relationship.  I'm just looking for sex.  But now I can't seem to get it here either.  Maybe this is just a rant from a bad experience, but I need some help finding that girl to give me what I need.  How do I best go about doing this hobby with the best results?  PLEASE HELP!!

(1) You used a credit card for an agency and you are married!

ARE YOU OUT OF YOUR FUCKING MIND?

Do you want her to find the credit card statements? Might as well sign over the damm house to her and the lawyers while you are at it! And if the agency gets busted well lookie here at this wonderful paper trail you so conveniently left for LE to find. Start a "nookie jar" fund instead! Always pay with CASH!

(2) Screw the agencies.  The girls have to see a lot more clients to make the same wages so they won't work as hard for you. Most indies work hard at repeats and referrals.

(3) I would stay away from "cheaper" high volume providers. They are notorious for upselling. Save your cash until you can afford a better one. The difference between a $200, $300 and $400 per hour provider is noticeable IMO.

(4) If you love your wife, tell her you have needs and that you did marry her and that you are more than just friends. I mean why stay married if you are going to be alone anyways?

I'm not saying that you aren't, but a lot people see 30-50 reviews; ave = 8.5, and expect a hot time.  One guy's 8 is another's 6.  Really read the reviews -- all of them.  Then you should have a pretty good idea of what to expect and how assertive you need to be.  I agree with most previous advice -- let her know what you want; pay cash; and stick to indies -- at least until you gain more experience.  Unlike the previous poster, though, I can easily understand staying with and not confronting your wife.  Many long and otherwise very satisfying marriages exist without sex.  There's also a significant financial consideration.

There are quite a few extensively well-reviewed indie providers in the DC area.  Best of luck!

Thanks for everyones help and input.  I think I will try and stick with independants for a while.
Thanks again
