When I meet with a gay man

I am 23 years old (male). Its a 1 year back. I want to maked my career in Call centre. So I decided to join a call centre training institute. There were a trainer who has the great personality. After 3 days he invited me to drink and he said to me, i will give you proper information regarding about call centre. I ready and gone with him. When we drink together i am in sozzled he said to me that he is a gay and he want something to me. I am not understand that time, he take off my clothes and he started to suck me. I enjoyed that time and I take his butt (fuck him). It was the first time when i fuck anyone.
But after that time I feel very guilty. I am not able to face him. So that I leave the institute.
Now, I am not able to forget him,I want to make sexul relationship. Now I want to know u its a natural or I am also become a homosexual guy.
There I want to tell you I like girls very much. I want to sex with the girls. But I didn't able to forget the trainer.

If you want sex with men and women this is called bi-sexual. If you put each person at a scale with completely heterosexual on one end, and completely homosexual on the other end, most people are not completely at one end of such a scale. Accept yourself the way you are.
