Recently my boyfriend confronted me about lying to him about cuming. When we had a conversation about it later he asked me if I knew the difference between having an orgasm and cuming. I said I did, but I really don't know the difference. I am really confused, the only reason I lied to him before was because I didn't know if I was cuming. I know what it feels like to have an orgasm.. but now I am all confused because I didn't know there was a difference between orgasming and cuming. Please explain this to me.

There is no difference. They are one in the same.

Its just a another word for orgasm no difference.
