Wheres the line, promiscuity.

[Steve-OOO1]

I'm not sure if i spelled that right. But anyhow, my question is how do you know where the line between being sexually active and being a slut is?

For me now i have been with alot of girls, but i have morals. I dont cheat and i dont lie. Whatever happenes between me and said women are between me and that person only.

Even though I am a good person, i still feel like im a slut at times.

Should i be feeling this way?
