Friends With Benefits Yay? Nay?

I was talking with a friend of mine the other day, and she said that she would have a friend with benefits. Her reasoning was no strings, she said it would be a perfect relationship. I told her I have had a relationship like that before and it did have it's perks. I feel as if, if I'm going to be in a relationship I want it to be monogomous, but friends with benefits is something that works too. You don't have to worry about answering to anyone or explaining yourself to anyone. But what happens when one party falls for the other. Most of the time when sex is involved us women tend to fall for that person we are physical with. I'm a woman of my word and when I say something is going to be a certain way I stick to it. I will be real with a man and tell what I want out of the relationship and what I expect and what I won't stand for. No matter what type of relationship I may be in I ALWAYS ALWAYS ALWAYS demand respect from my male counter part. Remember ladies you must respect yourself first if you want respect from other people. Whatever your preference, you have to ask for respect above all things. With all the perks it has, friends with benefits can get complicated. You can slip up and fall for the person. You can expect more from the person when they weren't expecting to be giving. so my question for you my loyal readers, would you have a friend with benefits?
