Would you hire a male au pair to look after your kids?

One of my students, a 20-year-old Austrian male, is heading to the U.S. in a few months to work as an au pair for a year. He wants to improve his English, and experience life in the U.S.A.. The other kids are having a grand old time teasing him about it, and telling him nobody will want him because he's male, as they'll be afraid he's a pedophile (judging by the girls I've seen him with over the past three years, his appetites are "normal" and healthy).
I've helped him with his applications, and really think the guy has a lot to offer. He's grown up bilingual (German/Serbo-Croatian), speaks English reasonably well, and has a basic command of Spanish. He's dyslexic, though. He's a licensed car and motorcycle mechanic, has an international driver's license, advanced driver safety training, and advanced first aid training. He's into sports, dancing, and computers, is outgoing, funny, has excellent manners, and is a very good listener. He's been the state iniaca champion for a couple of years, and trains kids. When filling out the forms, he said (and I believe) that he would have no problem whatsoever with being placed with a single-parent family, gay or lesbian-headed family, or one of another race or religion. He says he's not experienced with infants or young toddlers, and would be nervous about dealing with special-needs children, or 4 or more kids at once, but otherwise he's game. Pets would be absolutely no obstacle, either, especially dogs and/or cats.
All the other teachers think like I do - he'll be just right for such a position, and will find friends and adapt quickly, so he has already gotten excellent letters of recommendation.
My question is: Would you automatically exclude him because he's a young male? This question is really worrying him.

It's extremely difficult for young Europeans to get a work permit in the USA, which is why many take the au pair / summer camp counselor route. Those from Germany have to go through a government-approved agency based in Frankfurt, and it's a lengthy process, with a lot of red tape involved. They do have some say in where they're placed (my student has just been offered New Jersey or Florida, and has chosen the former, because of its proximity to NYC, Philadelphia, and Washington, D.C.; apparently a couple of families are interested in having him, primarily single moms with boys). They get free room and board, $159 pocket money, a $500 English course, two free weekends a month, with 1 1/2 days off during the other weeks, all in exchange for 45 hours a week caring for children and doing light household chores. The idea is that they'll be able to improve their English, learn about the culture and way of life, and perhaps teach the kids a bit of a foreign language, should the parent(s) so desire.
