Dating with dangerous consequences - is she worth the risk?

Your friends sister.

Why not to: Blood is much thicker than water, and by going there, you are seriously jeopardizing their relationship that has been established for many years, and there is no guarantee yours will last.

Why you should go for it: If there is mutual attraction and you both have common interests, it's a sound foundation for any relationship, according to Dr Pam Spurr, author of Fabulous Foreplay. "If your friends sister is younger than you, which is normally the case in these situations, there is every chance she has had a secret crush on you".

Are you a bit of a love rat? well you run the risk of your mate becoming protective of his little sis so she doesn't get hurt. You need to prove you're not out to simply put another notch on your belt. You need to prepare your friend by discussing how career focused you are, and indicate that you have the ability to provide for her. Big brothers are typically over protective of their little sisters, so your friend will feel more comfortable if his sister dates someone he knows really well, which is you!

Your child's school teacher.

Why not to: Parent-teacher nights can take the focus off the purpose of the meeting if your child's teacher is giving you bedroom eyes at the same time as assessing your child's report card. The ramifications can be damaging if the teacher is a heavy influence on your child's life, who will suffer if the romance goes sour.

Why you should go for it: If there is some chemistry building between you and the teacher, and you're a single parent, apart from using online dating sites , the opportunity to meet new singles doesn't come up all that often, and given that you have already established common ground, it would be hard to pass up the opportunity.

You only have a few minutes to seize on this window of opportunity, so utilize your speed dating skills after you have been through your child's report card, the fastest way to make an impression - according to Harvard psychologist Dr Zick Rubin, is to "establish 5-6 seconds of eye contact, and to divulge personal information", something really simple like, favorite foods or recreational/exercise habits.

The boss's daughter - tread very carefully with this one!

Why not to: Your boss controls your finances and could make your life very uncomfortable both financially and during work. Undressing your boss's daughter with your eyes is one sure way not to get a pay rise.

Why you should go there:

It pretty much goes without saying that she is off limits, many will look, but touching is risky. She holds power by affiliation, and bedding powerful women is high up on the list of 'must do's' for sexually active men. You can count on the fact that most of your competition will be too scared to go there, so you will have a clear and unchallenged run, and she will appreciate your audacity and risk taking - best of luck with your new father in law.
