Is it too much??

I bought a decent-sized rabbit vibrator while in Japan (my first toy). Now, my usual way of self-pleasure is by simply touching myself-- I rarely finger myself, because I feel nothing when I do that.

Guys, I need tips. Would I be okay with suddenly using the vibrator? Would it be too much?? Too painful?? Should I start with smaller vibrators?

I still have my v-card, thus my concern about the size. It wouldn't rip my hymen, would it?

The vibe's still in its box. I really want to use it, but I thought I'd be more cautious.
