you why he allow a relationship with a 21 year old ...coz he was curious and wanted to explore...and this was the only way...for any straight person its very easy...coz you see it on TV,Read it in newspaper and parents and friends disscuss this...and secondly you are saying that he should change his lifestyle and become straight....tell me can you become gay/lesbian if you change your lifestyle...will you enjoy it....i know your answer is NO..and a person mentally grows abnormally only when he/she is raped or sexually abused and he didn't experiance that ...so he is perfectly normal
