She needs a well hung bull

Wife has complained that my cock is not satisfying her and that I don’t know how to use it with what I have. She gets sexually frustrated since I cum too fast, less than a minute. She asked if she could have a bull that knows how to use his cock with a good size, 8” long or longer, and 6” around or thicker and can last a long time. She can only do without condoms, so please be tested.
