I've never written a "How to" before and didn't really set out to do so. It was just a collection of thoughts while trying to come up with a plot for a story. I put those musings together and came up with this:

OK, if you expected a handbook, you're not going to get it. Ultimately, it's up to you to come up with your own ideas. I'm not saying that any of the following scenarios have happened to me, but they are most definitely possibilities for having a little fun.
For the purposes of this discussion, let us assume that the Sex in the title means sexual gratification between two people (e.g. one or both of you have an orgasm).
I suppose that some don't really care if they are caught "in flagrante", but to the majority of us this could have dire consequences. However, in order for such acts to take place, there must by their nature be a certain element of risk. It's this risk that makes such an experience so deliciously erotic. Not just at the time, but upon recollection when looking back.
Having a little alcohol in your system will always help to break down inhibitions, but too much is likely to make you take wild risks -- and then us men may have problems fulfilling our (or our partners) expectations anyway.
We can probably break down the acts into the following categories; masturbation, fellatio and intercourse.
OK, hands up all those people who have achieved all three of these acts, in a public place - but not necessarily at the same time? Wow! That many huh?

Masturbation
Not a particularly difficult objective to achieve, but why not try and find a way to make it even more exciting? As a suggestion, you could try doing it during a train journey.
You probably need to be familiar with the line and its stations. For example, you don't want to find yourselves at the point of no return just as the train arrives at a busy station. For a woman, it's probably not quite as bad as you can just look uncomfortable until the moment passes. But for a man, the idea of your cock shooting off like a loose canon in front of a couple of shocked and outraged grannies, come dribbling out from behind the fingers that are trying to conceal your manhood, is enough to put you off of the idea of risk taking for life.
You may also wish to avoid contemplating your act on a section of line where others may be able to view down into the carriage. In the age of the mobile phone, a police officer could be called and be waiting for you at the next station.
The carriage itself doesn't need to be deserted, although a very busy train may prove more of a challenge (but even then it's not impossible). Imagine this scenario; you board a busy tube train and find yourselves crushed into a corner by the opposite (non-opening doors). A hand nonchalantly dangling down between you can work wonders, especially if you are wearing an unbuttoned overcoat. More extreme movements (such as the pulling down of a zip) can be made when the train lurches.
Wanking can, of course, take place when you are fully clothed. It probably helps to have clothes that are fairly loose and not too thick, although even Jeans should be OK. The only recommendation that I would make to men on this front is to wear dark trousers. Underpants will help to collect your ejaculation, but going commando could cause embarrassing wet patches.
