Did I or not???

Ok ladies, little preface: I’ve only masturbated twice in my life & I don’t own any toys, im trying to get out of the stigma of it being wrong since I grew up religious (if anyone has tips on the too that would be great) but anyways, I was just trying things out & I got to the point where my legs went numb & I had this crampy feeling, like a good crampy feeling in my lower stomach, like it felt really good but I just don’t think I got to the big O, everyone says oh you’ll know when it happens but I just have no idea & I feel lost. I’m not super innocent & I’ve had sex multiple times but I feel like it would be much more enjoyable for me if I actually knew my body before anything. I’m getting to the point where I want to quit faking it & be honest with my partner(s) about it but how am I supposed to help them if I can’t even help myself!!
