When talking to girls 19-21 at bars/clubs they seem like they are into me but lose interest when I let them know my age.. I look younger then I am (maybe 21-23). It's hard to avoid the question, I usually ask them to guess but usually end up telling them the truth. All this PUA BS I've read made me think that being 3-5 years older is an advantage but out in the field it doesn't seem that way at all
