I can only orgasm lying on my stomach when i masterbate. I've tried on my back before and I just can't get the same pleasure from it. is this something that will translate into my sex life?

You have to remember that masturbation and sex are two totally different things. What you feel when you’re self pleasuring yourself will feel vastly different from having a penis or even another persons fingers inside of you. The sensations, the energy, your mindset- all of it, will feel nothing like when you’re getting yourself off.

Especially when it comes to fingering yourself, you’re not able to get the same angle another person can with their fingers, someone between your legs cab actually fully penetrate you and hit your G-spot.

I personally wouldn’t worry about anything like this because it will only cause you undue stress which might affect your first time having sex. You might be so worried about what might or might not happen that you won’t be fully engaged in intimacy with your partner. Just remember, it isn’t the same!
