Why loneliness increasing?

I am a 25 year old , have a decent income, very few friends and a small family but overall happy. I had girlfriends in teenage and I was a total beast. Day by day I am finding myself very very lonely. After office, after a hectic day there is no one to talk to ( meeting with friends is now a cannon event) As a male I can't deny the fact that I thrive for female touch, smell and hold. No one to witness my life struggles or peaks, I am all by myself. Its very tiring to live. Either no one is liking me back or I am unable to like them(genuinely , not lust). Anyone has the answer?
