ps my husbandloves it thats all that matters
I discovered squirting through masturbation as a teenager as well. I wasn't able to do it with a partner until my mid 30s and I think it's just because it was something I really needed to be completely comfortable/relaxed with my partner, have complete trust and love for him. It also took being comfortable with and understanding my body. And all that took 20 years! Although it sounds like for some women, they do it often and have no control over it. I remember worrying it was pee but it usually left no color or smell so I decided even then it wasn't. And have done some researching since and believe it isn't.
For me, I was able to do it through "pushing" out my PC muscles instead of holding them in. Make sure you pee first...I know I can't pee anyway when I am very aroused or just had an orgasm. I keep pushing out and eventually I get very aroused during oral sex and I have to to pushout (and my boyfriend is intently licking my clitoris) when I feel the urge and then I squirt a few times. I have control over that part but soon enough the act of squirting causes a huge orgasm and once I feel it starting, I can no longer control it. From what I've read, other women "push out" at the point of orgasm and at that point squirt or gush.
My boyfriend also loves it, drinks it, and loves it all over his face.
