My husband is away, I want to surprise him when he gets back! and I honestly have never asked for tips on this I thought I just couldn’t 🤷🏼‍♀️

My husband never finishes from oral but I think I’m not trying hard enough or doing it right ? Has anyone had this problem and fixed it ? I never give him oral because I feel like it’s pointless since he doesn’t finish and it makes me feel bad...
