I agree.
That's what I said.
I think OP may be talking about introverts and extroverts.
That's a whole different thing to being born unable to socialise.
I'm an introvert.
I met men through friends, work, hobbies,on holiday, because online dating didn't exist.
I understand it's harder in your 40s but to be a success at work or in your social life the first rule is you need to 'show up'.
That means getting out there, expanding what may be a narrow set of interests so you actually put yourself in a place where there are women!
Have a look at the website Meetup. There will be loads going on in your area, from meals out, concerts, bands, walks, theatre, talks, reading groups, etc.
Time to spread your wings a bit.
