me and my boyfriend did it for the first time (for both of us) tonightt. Everything went perfectly, it didn't hurt and i didn't bleed. I'm just still paranoid about pregnancy...we used a condom and he pulled out before he came. I probably shouldnt be nervous, but due to being extremley athletic my periods never come regularly and it is common for me to miss many months at a time. How can i be positive i'm not pregnant!
