He's gone shy, because he doesn't wanna let on that he's into you

yeah, the "lol" came across as if you were laughing at his suggestion - bad move. Reply back with "that's a shame - i was hoping you had something fun in mind ;)"

You need a guy who will take charge and stay strong...this is not him...on the next is what needs to be said

He's too shy to make a sexual joke.

If you like him, get freaky with him. If you don't, don't be too mean or you'll kill his confidence.

He wants you to either give him a handjob, blowjob or have full out sex. If you like him you'll make him happy. You scared him by saying "LOL". Text him and say "I'll do anything you want ;)".

He seems immature

I think he got a little shy! hehe
