Does get better after marriage? ?

My boyfriend and I have had premarital ...and yet...I don't feel any pleasure. He is considering not marrying me because he feels guilty for not being able to pleasure me. He read somewhere, any woman can be ually pleasured. I think will get better after marriage. I think a lot of factors hinder us...such as it's during the daytime, we don't have much privacy, we use condoms, we are stretched for time, and we have a lot of thoughts in the back of our mind (such as pregnancy, our religion, our family). I love him and he loves me, but how important is in marriage. Will it get better? I need some advice here...please help me. I don't want to be the reason I broke up with the love of my life.
