Asking again.... Not sex in the shower....

Okay so my husband pulls out when we have sex. He's afraid to put it in right after (even when we take a shower AFTER sex) cas he thinks his sperm is still there and I will get pregnant based only on that fact. I know there is already a chance with the pulling out thing but we've been doing that for years now and haven't gotten pregnant from it. On top of that sometimes we use condoms, so yeah we're safe when it comes to that. Anyway can someone tell me I'm right?
