I honestly think it boils down to attraction, how comfortable and safe she feels with you, how much she knows her body and is comfortable speaking up and mental blocks. Which is a lot to address, right? Lol. Usually if she can make herself cum from masturbation she can cum with you she just needs to show a breh how.
I stopped accepting orgasm-less sex years ago. I just started speaking up—telling him how I want him to fukk me, moving with him, (I think movement really helps) making him do foreplay before eating me out or anything else and helping out. Like if he’s eating me out, I’ll finger myself, move my hips, etc. in certain positions I’ll rub my clit while he penetrates. Also incorporate toys. Ive let my guy use a toy on me to make me cum and right before I do, he penetrates. That’s pretty amazing. I find girl on top-and letting her have control is easy to get off from. Also the spooning position, when she lays on the side and you enter from behind is usually really good for it too.
not even from masturbating? Interesting.
