My husband is twenty-five and I am twenty-eight. We got married a little over a year ago. We have a really good sex life except for one thing. He insists on a blow-job every time we have sex. I have always enjoyed oral sex, and have had a number of male partners in the past. The trouble is, unlike my previous partners, he always shoots a very large amount of cum in my mouth, causing me to gag. I've even insisted that he pleasure himself before we have sex, hoping to lighten his load. Still the same result. Help!
