I am a 24 years old guy.its been since last six months that i lost all intrest in sex.Though i was pretty normal before,i dont even feel thinking about it any more.If ever i start to think i feel as if i am stressing my mind.This is seriously very depressing but i am keeping positive hopes that i will be all rite again.Could you please help me with this issue?.If some thoughts ever come in mind some tym i dont feel any sensation in the heart and any where which was dere before.Do i need a medical check up or is this some thing psycological???I am also getting a feeling as if these things are not for me any more!!!!Please guide me how can i get lust for sex again???
