You know why people get pregnant on accident?
Because they aren't thinking about it.
It's possible that you're too tense, stressed out, what ever.
So, here's what you do:
go out with your guy (dancing, have a few drinks to loosen up) have an awesome time.
Next: go home and get him!!!
See, your inhebitions will be gone, you won't think about it, and you'll have fun!
My friend tammie swears thats exactly how she got both of her kids (who are now adults) and that's what she told me to do when my husband and I decided it was time to try.
I think it works.
