Insecure

So I’ve had sex a few times and I’ve been told there’s a difference between cumming and having an orgasm. So idk if it’s true or not, but I can’t get wet. Like it takes so fucking much. Is something wrong with me? I’ve read about how the birth control impact in your arm sometimes doesn’t help and actually makes you lack in getting wet. I’m scared to have sex again because like High school boys talk

I just, I don’t know what to do. And sometimes if I’m laying in a certain position myself and insert a finger it feels loose but at the same time it’s not. I just fuckkkk. I don’t know, I think something is wrong with me and I don’t know how to ask my mom to make me an appointment with my OB to check and make sure my vagina still works 🤦🏼‍♀️
