Am I wrong

I’m 21 and my husband is 24. We have been together for 2 years and some. Married for 5 months now. Lately I have been wanting him to go a bit longer in the bedroom. I’ve brought it up to him because we usually go one round and never got past 3. He thinks that I’m asking too much of him and that I should be grateful that he is a good husband etc. I am but I feel like it’s heights we haven’t reached yet together. I’m more experienced than he is and I know what I’m missing out on. Am I wrong for wanting to experience this with my husband? Am I asking too much?

Since some people are BLIND we rarely have sex more than one time
