Delayed Ejaculation

Jennifer • I`m 31. Married to my high school sweetheart. Have a 5 year old son
So my husband and I have been TTC #2 for almost two years. I found out last night that I'm ovulating and HE. CAN'T. CUM. What can I do to help?! We've NEVER had an issue with this before. I know he feels terrible because he's been wanting another baby longer than I have.
