Conclusion: To control sex is not unscientific. More you become liberal to sex more you get addicted to it. Disciplined sex is the best. You have sex only with your partner with whom you have lifelong committed relationship. This will bring happiness and harmony in your life. Happiness and pleasure are different; to get happiness you must leave or harness the pleasure. You are not losing anything if you are not having sex. Those, who belive you are a loser, are object of compassion. Have compassion on them. It is same as if a drunkard come to you at midnight and said " dude you are a loser because you don't drink". It is same as a drug adict come high to you and say " dude you are a loser, you are missing heavely pleasure" Don't make modernization as an excause of your weakness. There is nothing old and nothing new. Moral and immoral people exists all the time. There were majority of people at the time of Buddha who used to practice immorality. There were very few people who were moral. Since history talks only about moral people, don't generalize it. This is true for all the time. To live a life of morality is difficult, that's why there were/are always few people to observe morality. However, without moral life don't except happiness in life. Immoral life may give you a lot of pleasure, but not happiness. Without morality mind doesn't get calmed down, and no happiness come from the restless mind. So if you have to choose morality and immorality, chose morality, it will give you long time welfare.
