He's not finishing...what do I do?

HHE • Married to the love of my life 💕

My husband has been unable to finish. We removed condoms and just relied on my pill and spermicide so he could feel everything. We've tried varying amounts of lube to see if that helps. I tried spicing things up with lingerie and candles and romantic music and sensual dancing. I gave him oral until he was closer than he had been then we switched to intercourse to see if he could finish better.

Over an hour and a raw penis/ thoroughly pounded vagina later, he still hadn't come. He was exhausted after a full hour of trying and a day of work so we just had to....stop. He helped me finish as he always does but I just feel so guilty and upset .

It's really affecting his confidence and I have no idea what could be wrong or what to do better. Help?
