Your choice of pubic hair is your own. Don't feel you need to shave just to please someone. Talk about it together and see what your preferences are. While you're at it, talk about boundaries and what you're comfortable doing. Make sure to go slow, use plenty of lube, and become fully aroused before attempting penetration. Foreplay is important and should help minimize or eliminate pain your first time. Make sure bth of your hands and genitals are clean as well as toys you plan to use (if applicable). Overall; have fun, laugh, enjoy the awkward experentation, and accept that you may not orgasm. That's ok, practice makes perfect

And pee after sex. ALLWAYS. Every time.
