Glossary Term: multiple orgasms

So my husband and I have been married for about 8 months now. It seems like every time he gives me oral sex, I end up orgasming within just a few minutes. Now, as great as orgasming is, I feel like after I orgasm so quickly, I am not as stimulated by penetration. Also, I really enjoy oral sex and I wish the experience could last longer. My husband and I waited until marriage to have sex. But before I was following Christ and before I met my husband, I was sexually active, including oral sex, and this never happened. So my questions are: 1) is this normal? is “premature ejaculation” a thing in women? 2) are there any ways to fix this and/or last longer? and 3) in women, if you orgasm once, is there a “come down” period? How is it possible to have multiple orgasms in one “sex session”?
