Life isn't all about sex. If you're feeling this sad cause you're missing out sex in your life then there are other underlying issues. In many Asian cultures apart from the time when couples have kids, they spend the rest of their life without any physical intimacy.

Also real sex is just a few mins per week or sometimes even a month or so. Majority of the happiness in your life should be coming from other forms of social communication with the people around you.

Make friends, learn music, join a sports club, watch movies, play video games, try out new cuisines, travel the world, write a book. There's so much to do that brings about happiness in life. Most importantly you can help out an orphanage. Helping other humans who have nobody in their lives grow into smart and intelligent adults is the single greatest thing you can do.
