That for many men, not all, but a great many, the primary consideration and motivation for dating is sex. This is especially true of younger men.
Therefore, if your intentions for dating are purely fun, or to establish a long term relationship, do not present to a man the possibility of a sexual encounter where no such possibility exists.
Do not do anything with which you are uncomfortable or agree to anything out of politeness, as changing your mind when you’re in bed together is probably inadvisable for all concerned.
I cannot stress strongly enough how much the desire for sex impedes the male brain; I’ve made far more stupid decisions in my life based on my libido than I ever did in pandering to my addictions. Do not expect men to see sex the same way that you do. They don’t.
I would also recommend very strongly to avoid going anywhere with somebody you don’t know and have not met before; if you are meeting somebody for the first time, via a dating app for example, meet them in a public place, don’t accept a lift in their car or go to any secluded places until you know them better.
Most men are normal people and not predators. Some are, however, and in today’s online world it is easier than ever before to hide one’s true character from another and reveal it only when it’s too late.
