Why would you tell her it wasn't good for you? You'll just make her self-conscious about something that she has no control over. Lots of guys really like squirting and plenty females wish they could. Don't ruin a good thing for her.

I would say don't say anything. It's only going to make her feel uncomfortable and self-conscious.

Now, if you get uncomfortable hearing that she's telling others about how you "rocked her world", you could always just tell her that it makes you a little self-conscious and uncomfortable that she tells other people about it.

Being that I am the type to "squirt" when I really get into it its not a bad thing and I would just keep that to your self. Its something that she can't control and shouldn't feel ashamed or akward about.. Trust me I use to feel weird when I did that the first time.. Just glad I was with a guy that really liked that kinda of thing..

As for her telling other people about it. If I was you I would just tell her that you really dont like personal info put out there like that and what you do in the bedroom is your personal business not the worlds.. If that upsets her then sorry but thats stuff about you..

Hope that helps you out some hun

Do you intend on sleeping with her again? Because, if you don't then yeah no point in ruining her high.

If you do, then you need to say something.

I enjoy it when I make a girl squirt. I don't think you should hurt someones feelings with something they don't have control of.

If you're not comfortable with her telling people, that's a separate issue from the squirting. As everyone else said, definitely don't tell her you didn't like the squirting. If it really squicks you, just don't sleep with her again. Don't lie to her, just tell her you would just rather be friends right now. I, for one, think squirting or soaking is about the hottest thing in the world (but then, there's really nothing a healthy vagina can do that will turn me off. I consider it all part of the very wonderful package). And given that she's raving about your skills in bed, it sounds like her squirting was probably a huge compliment to those skills so props on that. If you're that good, you may have a hard time avoiding the super-soaker reaction, so I'd like to gently encourage you to maybe learn to appreciate the beauty of what a sexual woman is capable of, but to each their own. If it's not your thing, it's not. I've been with girls that were self conscious that they got too wet, that they squirted or gushed, that they had a smell or taste (again, healthy, not talking about an infection), that their muscles contracted strongly, paranoid beyond reason that they would spontaneously begin menstruating and otherwise freaked about just about anything else their vaginas were capable of and given my attitude about it and my total and complete love of sex with women and everything to do with it, that can be pretty frustrating and I feel really sorry for those women. So if she's confident about her vag and her sex, just let sleeping dogs lie, and don't engage her sexually again. Ok, off the soap box.
On to my other point. If you don't like her bragging about your sexual prowess, just tell her, hey, I'm not comfy with you telling everyone about what happened privately between us. There's absolutely nothing wrong with not wanting the whole world to know those intimate details, and you don't need to bring up the fact that you didn't like her squirting to tell her not to talk about you like that. I wouldn't forbid her from talking about it, because, hey, a girl needs to have girl talk sometimes, ya know, and if it was really that awesome for her, well, naturally she needs to tell folks about this amazing experience she had. Just ask her maybe not to name you when she talks about it or not to point out that she was talking about you if/when those she's told meet you. Just tell her it makes you self-conscious or whatever, or you're just not comfortable with other people knowing. That's a completely separate issue from the squirting thing. Leave the squirting alone, but if you wanna keep your sexual exploits private, I see no reason not to tell her that without bring up the other.
