Thanks for all you guys... I had even consulted a psychiatrist for this problem(??!! Hereafter its not a problem at all) in my local area(Tamil Nadu, India) and even he himself didn't answer properly. I have even thought of suicide for being attracted towards gay. Actually when i was with my friends, i'll tease girls and really like it. I really feel gay thinking only when i am alone. So whenever possible i'll be with my friends.As a engineering student, i'll have several things to study, but i'll thinking of sex. There are so many medicines to increase the feelings of sex, but i wonder why no medicine for reducing the feelings for students, like me. I have abnormal sexual feeling, masturbating 4 or 5 times a day , even before the semester exam day, if i feel sexy... How to avoid excess(not normal ) sexual feelings and concentrate on study?I'll never share my sexual feelings with frnds, bcaz if they know i am a gay, i am sure that they wont even sit nearby me in bus/class room. Also, i'ts impossible for me to marry a boy in my culture.(suicide is 1000 times better than gay marriage, here). With your answers, i have concluded that i am bisexual, Since I am not attracted to all men/boys, only one or two extreme smart among 100 and almost all beautiful girls.Whenever i think of a smart boy, i'll visualize his ugly face/actions to hate him to get rid of gay feelings, right now.
