In my experience, it’s about behind where the clit is. If you make your thumb and index/middle finger into the shape of a tuning fork, insert the fingers, you can rub both at the same time. Some women enjoy this, though get permission before you try!
Also, don’t stimulate with your finger tip, as it’s very easy to unintentionally involve your finger nail. Use the pad of your finger, and yes, it’ll be a bit less comfortable for you, but way more comfortable for her. If you automatically switch to easier movements when you get tired, keep your nails trimmed and try to keep the contact closer to the pad than the tip (I know that nothing sucks more than getting your partner close but also getting too tired to keep up the movement to finish her, don’t scratch her in that moment).













Or make a duck bill/shadow puppet mouth. Main thing is to make your fingers and thumb parallel and also line up their ends so you can move your hand and rub the outside and inside of the vaginal wall right where the clit is. Tuning fork was the first thing I thought of looking at my own hand in that position lol.
