What does it feel like to masturbate with your fingers or an object?

I personally watch.. gay porn .-. and uhm.. I masturbate in a way where my legs are crossed and I think it started when I was 12. basically it's a hands free masturbation. I'm just curious on how it feels to have something inside your thing. Sorry for asking something like this, it's just that I can't ask someone I know about this matter and thank you? if anyone ever finds this question :3
