Well I am 38 and never had any popularity with women in regards to dating/relationships (got plenty of female friends though)..

I personally don't care, I am happy how I am, don't want a relationship.

All I know, and all I can tell you in regards to advice is that women like people with good self confidence, and a positive self image. Also if you have problems with social skills, you may need support/practice with that.

That's all I have to say.
