As others have posted, I'd be careful, not just of this guy but anyone new in your life - I'd take things slowly whether it was a friendship or any other sort of relationship. That said, maybe he is new to the area and looking to make friends, maybe he saw you as the most approachable of the group or maybe he is attracted to you. You say you look younger than your age - perhaps he does too. Anyway, I wouldn't worry too much about any potential age gap as a lot of people have great relationships with quite big age differences - if you get on well, can trust each other, have common interests or can accept each doing their own chosen activities/hobbies etc then why worry about age? I'm only 5 years older than my partner of 30+ years and am glad I worked through initial doubts/worries. Just keep your guard up but allow yourself to be happy, to make new friends, and who knows, maybe a relationship with a good-looking, sexy-voiced Italian. Good luck if you do go on a date.
