I don't want to use a condom for my 1st encounter. How do I make sure she doesn't get pregnant? Can I use pill before sex and i-pill after sex?

No. There are no pills for males to take that prevent pregnancy. But there is a greater issue than getting someone pregnant during unprotected intercourse. There are ahost of stds that you can contract, some not curable, that you can contract with yout ist encounter...And subsequent encounters.
