I am a 25 yr old boy. I feel like I have some hormonal problem vis-Ã -vis my sexuality. I feel real pleasure when I press my nipples and I get aroused .I get aroused when I imagine myself getting intimate with one of my earlier close friends with whom i had anal sex few times. At those times, I really wanted him to make love to me. I am confused .Please help me.

From your short description, what I could make out is; you have problem of gender identity. Your sexual orientation is towards homosexuality. Get your sex hormone profile checked (it is done through blood test). If you find any abnormality in sex hormones, you need to consult Endocrinologist (specialist of hormone related diseases). If report is normal, consult psychiatrist.
