Yes, this has "wrong" written all over it. She seems to be about increasing her "body count" to where she is the body count champion of all time.
No, I don't think I would have done it, even in my horny-ass twenties. But I was never confronted with such a situation so I can't say so with absolute certainty.
It's not like I never had casual sex. It's rather that what I was after even then was connection. Human connection is what everyone hungers for. The body count obsessives will always miss this.
In every sexual relationship I have ever been in, I never cheated. Because the relationship part of sexual relationship has always been very important to me, cheating wasn't ever something I wanted to do.
