Tread carefully Cindy. Is the male friend interested? Whilst you may be able to block this, you may not. Is it helpful - your call. is it OK?
A good measure (of anything) for me is ask yourself - "Would I be proud to tell my kids?" - if you have to also add ANY qualifiers, then you'd better start asking yourself some harder questions.
