Bit of an odd question but hear me out. Im sure there must have been some secretly gay boxers but has there been any openly gay?

I was recently reading a book called 'Looking for a fight' by David Matthews (excellent book I highly recommend it). Its a first person account that follows David Matthews himself (he is a journalist by trade) and he decides to become a professional boxer to find out from the inside about the business, with no prior boxing/sporting experience at the age of 31. He trains at the gym where Clinton Woods trains and Woods was saying that if there were a gay boxer he'd have a massive huge following and loads of fans due to the gay community. Got me wondering, has there ever been a gay boxer?
