Questions: Flirting

This is a fact, at least in my country (Portugal). Guys don't approach girls anymore, at least the good ones. They go to parties or wherever, and just stare and stare and stare at us girls, waiting for us to approach them.

This is so annoying and I am so sick of this. I'm very beautiful but I'm relaxed and funny. When I go out, I feel that almost every guy in the room is staring at me and looking at me. But not a single one comes to me.

My crush and I are good friends and I give him rides home from school a lot. He's 18 but only has his permit. He likes to leave his stuff in my car for some reason, like it's his closet.
One day, I was cleaning out the back of my car and found his windbreaker. I was thinking about him and remembering how he smelled the last time we hugged and decided to smell his jacket to see if it smelled like him. He has long hair and the collar smelled just like him and the sleeves smelled like his deodorant. It was like nose crack! I couldn't stop sniffing!

I feel weird for doing this, but it's so addictive! He took the jacket back and now I'm paranoid thinking he's either going to smell my perfume on it or maybe I got makeup on it from snuggling it like a 2 year old!

Since we are really good friends and joke about everything I half want to tell him to wear it, get it all sweaty and then give it back to me but not say why I want it. Does that sound creepy?
His friends tell me he's had several people drive him past my house and he's jogged past really early in the morning and threatened to ding dong dash me, so he "stalks" a little, too, lol.

He manages to either make double entendres with me or just straight up talks about sex on a daily basis, so I think he might be turned on that I want to smell him? What do you think? Should I just tell him his smell makes me hot?

My crush either sits side by side with me, or he will sit or stand right in front of the desk I'm at with his crotch right where I can get a good view. Always! Like he totally blocks my view by standing right in front of me while I'm sitting, so I have to look up at him (ego, power thing?) or, if I lower my eyes, it's stare at his junk time. Not that I mind, ha ha, just wondering if this is some signal he's giving. He's done stuff before like ask me to look at his right pocket when I'm on his left, so I have to look at his crotch again.

He also talks about his junk a lot, like I was eating some nuts and he came back from the restroom and I asked if he wanted some nuts. He said he had just touched his own, which seemed unnecessary to share. He talks about sex a lot with me and jokes about blow jobs a lot. Is he hinting at something? His eyes shift down to my shirt a lot when we talk. I think he thinks I don't see him peeking because I don't say anything.
