Male here, almost 60. First, I love it when a lady squirts. Not all do or will though and some don’t want to, think it’s wrong etc.
I’m no expert by any means but there are different ways to do this.
Two fingers inside the vagina doing the “come hither” motion work well, but with a twist for one lady in particular.
She would lie so her lower abdomen, just above her vaginal opening, was on my left pectoral muscle. I was lying on my back on the bed and she was lying diagonally over me with her head on a pillow over my left shoulder. I’m right handed so I was using my right hand inside her vagina.
I was able to push down with my fingers against the upper inside wall of her vagina and I could feel my chest on the other side. She liked that and with that particular lady, it had a really high success rate of making her squirt, like over 90%.
Surprisingly to some of you, that lady was my 1st wife, my ex-wife.
We all know penises are different, some have the proverbial “fireman’s” helmet for the head of their penis, others don’t. I’m circumcised (American, born in the 60’s and it was chop, chop for us back then). My ex-wife would lie on the end of our bed, I’d be standing with the head of my erection inside of her so it could press up against the upper inside of her vagina, like my fingers would when I used them. While doing that, I would use a hand to press down on the outside area just above the opening of her vagina so she’d have the sensation there from both inside with my the head of my erection and on the outside with my hand pressing down.
For HER, those two ways worked very well.
Long ago in the 80’s in college was the first time she ever squirted, neither of us knew about it or knew it was coming. We were warming up before intercourse, making out and I was using my fingers inside of her and she ended up squirting, a lot as in we had to take all the bedding off and then wash the mattress and we had to put a fan blowing on the mattress (it was a college provided mattress in my dorm room).
She was nervous, blurted out it wasn’t pee. I didn’t care either way, I loved it. She was on top of me and it flooded me too but I loved it immediately.
I say surprising that it was my ex-wife because she and I had a bad sex life overall but she squirted easily and often, to the point we had to take precautions for the bedding or the carpet etc.
