When you say you’re not sure if you can turn yourself on, but you have never masturbated, I suggest the only way to find out is to give it a go and explore.
You don’t say how old you are but it’s fairly normal for most girls and women to explore themselves, and often, it’s the ones who do masturbate and achieve orgasms by themselves who also orgasm when they have sex with their partner.
There’s a link, and it’s about knowing your body, knowing what you like and being able to communicate that. Don’t be alarmed if you can’t make yourself climax though, because not all women do or can.
But those who do would always say give yourself time to really play around. Try it in the bath, in bed, at times when you’re not going to be disturbed so that you can see how long it takes.
The biggest mistake most women make is assuming they’ll be able to achieve orgasm in the same time frame it takes for a man to. No, you’ll need MUCH longer, and he needs to know that. It’s an investment.
