Eaten out

Hello. I have questions to ask.

So my boyfriend and I are experimental in bed (still haven't lost our virginity). I just have some questions.

1. I am insecure that my vagina will smell or taste bad if he eats me out down there? Any tips?

2. How do you guys remove hair down there? I would never wax, and shaving leaves me with ugly and painful cuts, bumps and pimples?

3. Does your vagina get tight again if u haven't had sex after the first time in a while. My boyfriend and I meet up about once every 3 weeks. I hope after the first time my vagina will be looser and less painful. But I am scared since it will be at least 3 weeks before we see each other again, it will once again be painful?

4. Any tips for bigger penises. My boyfriend is extremely large and my virgin hole is still extremely tight. Help?

If anyone can please answer any of these questions numbered by the question, I would THOROUGHLY appreciate, thanks.
