(This is really embarrassing to ask aaaa)

So, I've only masturbated with rubbing my clit before. Fingering hurts and I can never find my G-spot.

I have two questions:

1. Are there any other (I'm fourteen btw, so I can't go out and get a toy or something) ways I can try to get off?

2. I'm really nervous that by only masturbating with simulation on my clit, I won't be able to get off any other way? I heard something about if you only get off a certain way, having sex or other ways won't get you to climax or won't be as good? It sounds stupid, I know, but I'm worried lol.

Ty!
