Can’t finish during sex, HELP

My husband and I just had our 1 year anniversary in July. We’ve been together for 3.5 years including engagement and marriage. As practicing Christians, we aimed to abstain from sex til marriage. We ended up having sex a few times in the months leading up to our wedding but we quickly realized it wasn’t what we wanted or believed was right. We are both the only person the other has slept with.

Anyways, since we’ve been married, we typically have sex at LEAST twice a week. While I always enjoy it, I’ve only finished once during sex. He’s really understanding and is trying his best so he helps me finish in other ways but it’s just not the same. Any tips or advice for crossing the finish line during sex?

Side note: I completely understand that not everyone is going to agree with us trying to wait til marriage. I just want to ask for please no judgments, I included that info to help better explain who we are. Just help a girl out 😅
