I really wouldn't hassle but I might make a few 'off hand remarks' that could be taken the wrong way :) You are right that its not really your business but sometimes you can remind friends about themselves and their safety.

For example, if she was all dolled up, ready to hit the clubs and bring someone home I *might* say

"oh, you look nice, very tarty" or

"well, should pull in a few snake oil merchants with that outfit" or even

"very nice, you could easily work at Hooters" or how about

"wow, I'm sure you look like that star..what's her name again, you know, in that porn movie last year, you look JUST like her!"

Or even just ask her

"how often do you get tested?"
"Does the standard STD test do AIDS or do you have to ask especially for that one?"

Because you know if she got all angry and upset about what you said, your come back is to say "I care so I ask" or "I thought you understood how I felt about all this"

Up to them really though isn't it - a bit of a push maybe but everyone is entitled to their own life :)

I probably couldn't resist saying something sooner or later, but I'd do my best to keep it to a minimum. A big part of it would also be how they feel about it though. Some people are pretty open and don't find joking about it to be at all offensive. Others do.

If it was a sudden change, I would be very concerned. I think I would sit them down in private and say something like "this behavior seems new, and not like you at all. I'm concerned that maybe something is going on with you and you're not okay. Do you want to talk about it?"

If she told me she was happy with her choice, and didn't seem to be acting out of some new self-destructive drive, I think I would just tell her that while I want to be supportive, I am concerned that her choices could be unhealthy, and that I really hope she takes necessary precautions to be safe.

She might hate me for that, but I would feel obligated to say something. Sleeping around is not very safe, and I would worry about a friend who suddenly started flitting around.

This is someone I care about. The fact is that her or his actions could be detrimental. I think that if I see them spiraling into a pattern of behavior that could potentially be life threatening, than as their friend, I have the obligation to say something. It will be a conversation that they most likely will not want to hear. It may be difficult for them to see their actions as unhealthy and dangerous. But if I am their friend, than I care about their well being, those are exactly the reasons why I should say something. Because if I don't, who will?

I don't believe in meddling in someone else's personal affairs. But if they confided in me about their actions, this may be a sign that they are reaching out for help. Is there an underlying reason as to why they are being so irresponsible? If so, maybe they need that little push to address the real reason behind their actions. Sometimes when we are knee-deep in the situation, we can't see the big picture. That's what friends are for.

If after the conversations about your concerns, they are unwillingly to seek help, or they do not see the issue, than you curtly tell them, that you will be there if they need you, and you will support them if they wish to talk about it later.

When in doubt, ask yourself this. If I knew that this person was intentionally placing themselves at risk, and this behavior could possibly lead to their death, would I say something? If your answer is yes, than you have already answered whether or not you should address you're friends promiscuity.

Unsafe or extremely casual sex could lead to a variety of health related issues.

1. HIV/AIDS. While their are treatments and medications that slow the progression and treat the symptoms, there is still NO CURE.
2. STD's. There are several other STD's that could lead to serious medical complications, if they are not treated promptly.
3. Violent acts. Many women are the victim of sexual assault, otherwise known as date rape.
4. Self esteem and depression. Promiscuity could be the result of a depression or self esteem related. Depression can be extremely dangerous if not treated, both emotional and physically.

These are extreme examples of what could occur because of casual sexual encounters. But they are a realistic view of what the consequences could be for you friends actions.

Well, I have one sister who does this, she looks and acts the part. I do not say anything, but I just kind of avoid her when she is dressed like that. I would ignore a 'friend' who dressed or behaved like that and would not be seen in public with her.
