Why do people check you and don't leave a message?

Because they are just having a look...nothing else...

The same as we sit on park benches and play the game
boxers, briefs, commado..It is something we all do..
Do you send something to all the profiles you glance at..

Do men think if we view them, we are interested.. but too shy?

....ACH.. no, that is not it.

Maybe after reading the profile, there is not anything interesting or have anything in common.

maybe they are just looking around?

you should email them all, just to make sure your not missing out on anything...

Yeah at least I tried to. ..

Please guy...tell me what am missing

Yikes note to self
quit perving men's profiles...

You would have to ask the FBI, OP?? IDK

Dude...its just like offline...we walk down the street everyone looks at everyone else, but we don't walk up and talk to them all do we???.....
same here man....

Why not send a message to those people checking you and not sending a message?

If they don't send you a first contact message, if they don't respond to your message to them, then what does it matter in any practical sense?

Let's say you figure out some deep dark secret as to why they aren't messaging you...they're still not going to message you! They don't want to talk to you. One little bit of knowledge regarding one individuals motivation is not going to magically transform you into someone they wish to message and talk to.

Let's say you learn some one tiny little thing, some misunderstanding, or means to magically communicate yourself better, a means to make a simple change, and you make that magic change....do you believe they are going to come back and say "wow! I reaaaaaally need to message this guy now! I don't even want to finish this thought I'm so excited and want him to do me now, oh my fingers can't type fast enough!"

Other than that, if you want some sort of "there there, it's okay, you're smart enough, attractive enough, and dog gone it, people want you!" answer then feel free to tell yourself one or more of the following:

1. They are so attracted to you they feel they don't deserve you, they aren't good enough for you. Therefore they read your profile and flee into the confines of their darkened closet to drown in tears knowing the person they can only dream about exists but they'll never be good enough.

2. They are really dudes with fake female profiles just looking at everyone's profile to do research for their own profile, spying on the competition.

3. Computer error. Their keyboard broke. They tried to send you a message but some interweb god is pettily harassing the wee humans until it causes enough anomie that it can devour their souls, relishing in the fear and pain and confusion.

you can perv mine, i'll only email you every other time...

yeah right I would be lucky if you did that
promises promise

Yep every once in a while make eye contact smile and aknowledge
