I am normal at my house in front of mother and sister. But when i see other women or girl outside at home, while going to office or in public, I feel some kind weakness inside me. I get nervous and anxious. Please note that neither i have craving of sex, do not watch adult movies. I also don't have any or don't want any girlfriend, also m not gay. I have no desire of girls but then why i feel weakness and nervous. I dun know. I get alert when someone stand near me especially girls. I never touch them and always go away. I used to talk two girls normally but they sexually teased me causing me headache, nervous breakdown, depression. I have never feeling of sex with them but i treat them as my office collegues. I don't have any friends. I live with my family. I am introvert, less talker, silent nature guy and single. The problem which i quoted is since past 1 year.  D
