Heres the link source for Arthur C Clarke admitting bisexual experience I think its pretty clear  httpplayboycommagazineinterviewarchivearthurcclarkearthurcclarkehtml Heres the quote  PLAYBOY Have you had bisexual experience yourself  CLARKE Of course Who hasnt Good God If anyone had ever told me that he hadnt Id have told him he was lying But then of course people tend to forget their encounters I dont want to go into detail about my own life but I just want it to be noted that I have a rather relaxed sympathetic attitude about it  and thats something Ive not really said out loud before Lets move on   If you read the entire interview the topic of sexuality is discussed in greater depth Given the context of the article I think youve been a little harsh on other editors on this issue Of course I have to agree that nothing should be added unless properly sourced I think this qualifies
