I'm a big guy, I'm balding, and I'm still about 80lbs overweight and I'm 28.

That being said I've had some absolutely gorgeous women come up and open me. I've had this my entire life.. But I always want to steer it towards serious conversation and getting to know a person (The 'dating' path) and that shuts it down. Hard.

Once the hottest girl I've ever seen wanted to fool around with me and I wanted a date. She wasn't down to date, I wasn't DTF. She stayed after a party when it was just me and her, she was handsy and saying her friends ditched her with puppy dog eyes trying to get my attention and a ride. Me being me, I'm looking for more than a ONS, I tried to setup some time to hangout and she got all cold and distant.. Next time I saw her she was handsy and flirty, again I hinted toward hanging out later and her eyes glazed over like 'wtf dude'. That's just one of many examples =/

So just curious for input, why i'm ONS worthy but not date quality?

EDIT: You guys give awesome advice! guess it's boiling down to me being awkward, stiff and sometimes missing things. The persistent awkwardness may be the worst personality trait of mine. But lots of good advice and stuff to remember

Also to specify I've only had this kinda interest from 2 hotties, the others were average, but it fell apart with talking too most the time.
