Why just under 13 hours ago.....
I'm an insomniac so have to tire myself out to get some shut eye and even then some nights it takes a couple of "sessions" before I'm exhausted enough to actually sleep.
But I've always been intrigued by people who say they can't "find company" or "get intimate." Just as much as I'm intrigued by people who can hit a pillow and be asleep within a few minutes.
In my experience it's usually the nervousness of the "wanton" party (male or female) in asking for someone to give them company that puts the other person off. They feel you don't really want them and are asking them more as a last resort. Sort of like asking your grandparents to stay over because your lonely. You don't want them to think your a sad person with no social skills and you have too much pride to believe "it's come to this".
The other reason is just plain lack of experience. Just because we're adults does not mean we know everything. Rutting teenagers get "a lot more" not only because their drinking and "popping" so have lower inhibitions more of the time but because their in a sexually charged environment.
If you ever look at what passes for "teen entertainment" in magazines, online and on TV it's practically soft porn. So really it's just a question of asking the right questions for them as their living in that sort of environment.
Anyway, my advise to you would be don't give up on yourself and get a lot more friendly with people. I'm not the shy type so have no issues with getting along with people - or telling them off. But others who ask me and "win" often find it easier to make friends first and then sexual partners of their desirable friends. The "official title" of course is "friends with benefits".
The other way is to decide on the type of person you want to meet (everyone wants a handsome prince but be realistic with yourself). Like a marketing agent you need to make yourself desirable to that type of person. So do your research on where they go and what type of profiles of people they like and make yourself fit it.
This is why dating sites ask you to fill out profiles and they match you with others. The formula is not fool proof as you could be in love with a persons image rather than reality and will reassess after meeting such a person. The important thing is life is about relationships too and it's a skill few people try and learn these days.
