i know it doesn't sounds like much but if u are virgin your best bet is to just use your fingure until you can stretch yourself a little. start with one finger or 2.
but if your heart is content on a vib, than just go to your nearest sex shop and look around, there are pocket ones that may be better fix for you at this time.

"doc johnson go vibe" is a good size, i think anyways. but if that isn't you style just search the web vibrators come in all different shapes and sizes to fix any women and man..
