Crying after cumming?

Is it weird that last night after the most amazing sex with my BF I orgasmed and so did he inside me (with a condom) that I started crying. I don't think I even know why I was hysterically sobbing, he held me and cuddled me as I proceeded to cry for 30 minutes. Am I the only one? Idk what going on? Help?!
