This isn't overly difficult. Guys get turned on easily. They get turned on when you hint that you might be willing to have sex. (although I disapprove) :( The right suggestive look ("You wanna?") works. Attractive clothing works. A nice scent works. Making out definitely works. Showing up with nothing under a long coat works.
The bottom line, anything sexual can work just fine, but some guys get turned on by some acts more than others; so you need to know what your man likes.
If nothing works, then he either has Erectile Dysfunction, or he is gay.
Be very close to him. French kiss him with desier. put your tong into his throught. touch his friend through pants jeans what ever he wears and then. Put him on the couch chair and sit on no NO sex though. You want to get him SUPER exited. this is how you do it. There are many other but this is my favorite. I don't know about other guys
encase him in cement but make sure you use straws in the nose.
Wear a mini skirt and have him flip it up so it lays on your back as you're bent over while standing or whatever and let him rubb your p**** lips through your panties. Let him get a very close-up look while he's doing it!
Guys usually know what they're doing when it comes to getting turned on, but pressing up against him does wonders to help him along. Kiss HARD and really get up close and personal. You need to let him know you're really into what you're doing. ~_^
