Can SEX be so Good that it Makes you Cry?

I have an interesting problem. My husband and I have been together for 2yrs, married for 1 month, and having sex for 5months. When we first had sex it hurt and burned ALOT.Now that my body is finaly getting used to it, it feels great.Sometimes it feels to good and we have to stop. Seriously, it feels so good that I will cry if we dont stop. I trust my husband and he says it is normal(I am not his first).I want to know is it really normal? By the time I am ready to cry, i am already screaming. I don't thik I can seriously handle it if we don't stop.Sould I let him keep going, I am so confused, my friends haven't had this problem (I have asked!).
