You should take things as slowly as you need. As for your first question, sex can be anything from an internal explosion of euphoric pleasure as it ripples through your body and leave you in a bit state of blissful wonderment to a painful and shameful ordeal.
So much of it depends on you and who you are with. The most important thing is that you must want it more than anything you have every wanted. Take things slowly and let the anticipation build. If he is someone you want, he will be patient.

Be honest and open ! Tell him upfront that you're not interested in it. Honestly you can wait as long as you want to have sex. If he pushes you and keeps doing so he's not the one cause he doesn't have your best interests in mind.
