All questions about buy vibrator

To be fair
Every scene with him is hot
But still

ok so it should be as deep as it can get (not so thick cause i am not wide there much.....yet?) and vibrate madly, which one should i buy?
and other one should be as thick as it can be (small size? cause it hurt if i try to get it deeper) and again vibrate madly, which one should i buy?
