There are obvious ways to get a guy hard. However, before getting into that, it is important to note that sex is not always going to be the answer to getting your man. It is an important part of a relationship, but it is never going to be the be-all, and end-all of your time with him.
Men are animals, so they respond to direct pressure and attention. Fondling, petting, and touching him in certain parts of his body will definitely get results. Of course, try not to have a heavy hand or be too rough.
Rent a dirty movie
You know, this tactic works extremely well. Some men even get a kick out of watching dirty movies with women, or at least one woman. He can fulfill certain fantasies and with you in the same room, he knows that you will not freak or scream blue murder.
If you're going to try this method, be sure to follow through. If not, you'll be called something not too pleasant, and you could even get a reputation as a tease. This could ruin you in your social setting, and make it hard for any guy to want to be with you.
Pole dance or lap dance
Some guys like this done in public while others prefer a private show. Find out which turns him on, and go for it. Of course, it goes without saying that you need to practice first, especially if you're going to do in public.
Wear peek-a-boo clothes
These are clothes that if you bend over or twist a certain way, he gets glimpses of luscious parts of your body. Do it often through the night, and do it to other guys too. Your guy will get so hot for you, he'll be practically dragging you out the door, caveman style.
If you know how to flirt and use your body, do it. If you know how to make your eyes smile, do it. If you know how to sway your hips, do this too. Flirting also means saying the right words at the right time. Turning him on is also a mind game, so if you can tease his imagination, you're home free.
Give him a sensual massage
You do not have to be an expert masseuse to do this. You just need to now his trigger points and use it to turn him on. You can get a guy hard just by teasing and twirling your hands across his chest, fondling his ears, and finger walking from his toes to his waist.
