I do think this age difference is a bit extreme, but it's just innocent internet flirting it's not like they are getting married. Young boys flirt with older women all the time and nobody has a problem with it if the woman reciprocates. During the New Years Eve live coverage a couple years back comedian Kathy Griffin who was like 55 was tongue kissing 24 year old male athlete and there was no controversy around that. Madonna is 59 and her past few boyfriends were all in their early 20s. I didn't see anyone accusing her of having a perverted age fetish. She was welcomed to speak at the women's march and worshiped like an idol. But if an older guy even speaks to a younger girl it is perverted?

OP, if you are seeking society's approval, you won't get it. I am 29 and people would have a problem with even me getting involved with a girl that young. I have even seen it suggested (on feminist forums) that it is creepy for a 26 year old guy to approach 22 year old college girls. Trust me, you will not convince people to be accepting of you at 62 getting involved with a 19 year old girl. As long as follow the law and your conscience it's all good. But be careful not to mistake social pressure for your conscience.
