Honestly I have no idea what I did to make the guys that have liked me like me. They often times have told me that they were simply impressed by the kind of guy I was, and have even times accessed that by stuff as random and pointless as overhearing me describe why I enjoyed a movie.
But I know things that guys have done to impress me/get me to like them varies.
First and foremost, its usually also simply because of the type of person they are. What do they value in life? What are their goals? What are their values? Do we have stuff in common? can they enjoy my kind of fun? can I enjoy theirs?
But stuff that they have actively done was just simply knowing that they liked me, was very unapologetic about it and pursuing me. There's nothing more annoying than trying to figure/feel a guy out. They were Just very open and honest and made it very clear that I am the kind of guy that turned them on, intellectually and physically.
I think when a guy is genuinely into you, they'll do the right stuff. just the same, the guy you like, if he's genuinely into you, he'll be receptive. So I say a guy shouldn't have to go far out of his way. Just show genuine interest, however it is you show that, and the right guy will respond to it, the wrong ones won't.
