Looking much older than you are

[SmileyEH]

I've been travelling for about a month in Europe, and the entire time people have assumed I was much much older than I actually am. Most people assume late 20's (youngest guess had me at 24). I'm 19 with 2 years of college and about no life experiences to date (went to college, skipped classes, got drunk, got laid is about it). So...I'm not sure how to take this - obviously people are expecting me to have a 26 year old's level of maturity (right.....), and the girls I'm attracted to (17-21) are probably going to think I'm a creep. OOT community I need your wisdom in tackling this strange situation.
Also, if just pretending I'm 28 is the best solution then I need some cover stories or is pro p*ker player still good enough?
