Avoiding pregnancy!

My boyfriend & I just started having sex. He’s 17 & I’m 16. We both had the “talk” about how we aren’t ready for children, and want to wait. (He just graduated & I’m about to be a senior). Because of family blood issues, I cannot take any form of birth control. Which sucks! And we use condoms but sometimes they’re boring :( any tips? Like is there a specific time of month where we can have unprotected sex w/o getting pregnant? He’s a beginner & isn’t so great with the whole “pull out” method yet. But so far we’re strictly staying with condoms.

However, in that “baby talk” IF I happen to get pregnant, our plan is to keep our child, and marry. But we are trying to avoid pregnancy, but we want a better sex life. (Any tips, or comments are welcome!)
