Frustrated!

Ladies, I am sexualy frustrated! I'm going crazy. I am married,24. My sex drive hasn't been this high. Tonight, I went down on my husband,because it turns me on. Which it did, I got ontop of him and what not and then it was all wet and all that good stuff...but it's like I don't even like it...like my clitoris hides from his penis! He doesn't have it small or huge is a bit above average so that's not the problem. I have never came during intercourse! Never!. He does, always and im so jealous and glad that he enjoys it but I don't ever finish. I am so hard to even be close to Cumming. What do you ladies recommend? It's always been this way with my exe's too so it's not like he's bad at sex or anything. I'm going crazy. Help! And sorry for the long post.
