Your love life problems will solve themselves if you solve your broader social life issues first. A social life is a bit like most things in life in that you get better at it and find it easier the more practice you get at it.

Paying for sex or a pretend relationship is not some magic pixie fairy dust that will suddenly make you the life of the party.

On the off-chance that you may suffer from social anxiety disorder or exhibit an autism spectrum syndrome, you may wish to consult with your doctor at some point. But not straight away.

P.S. I was first "successful" with a member of the opposite sex when I was 26. shrug
