I think if she didn't like it she would say nothing at all. So there are two options left, either it's pretty average and she is just making you feel good (which is a nice thing anyway) or she likes it and is telling the truth (which is nice also).

I've been frequently seeing the same lady for 3 years. She always told me that I was good at DATY. About a month ago, she told me I was doing it "not quite right" and coached me. Totally different reaction from her when she cums now, she admits she faked it most of the time in the past. I can tell the difference. When I asked her why it took this long to tell me, she said that most guys aren't able to take criticizm or instruction without having their ego's hurt. It took this long for her to trust me enough to tell me the truth.

Personally this is why I have requested no more DAYT because some know what there doing and some dont.
I would suggest asking and believe me youll know when your doing it right. Lol.
But on the other hand I know I love giving a female head espacially when she is all wet and juicy. Yummy!
But each female is different and the most important fact is both you and her should feel like you can trust one another because if she is willing to see you she should be willing to open up and tell you how to make her come whether its her getting head of you giving head.

and so are her likes and dislikes. Never be afraid to ask for a little guidance. Ladies ask us what we like all the time, and I think they appreciate us asking what pleases them as well. If you're getting complimented by a number of ladies, there's a good chance that you are doing something right.

And no, it's not a dumb question. The only dumb question is the one that you don't ask.

I don't understand why you're asking the whole wide world if the ladies might be kidding you? How would we know?  You'll know if you're any good because you'll like it and you'll know that she likes it. Are you paranoid that you aren't good?  The other thing is, being good at anything means that you never stop getting better, and that means asking questions, and in the case of cunnilingus it means gently inquiring of the one you're with if she has any suggestions on how you can better please her with your mouth and tongue.
