I have a FWB situation with a woman who is 12 years my junior (I'm 32 and she's 20) and I can't shake this weird feeling I have about it. I keep thinking about how she is younger than 3/4 of my sisters and it's giving me this feeling of cognitive dissonance.

I've talked to male friends and its unanimous that they think it's something to be proud of and my female friends think it's more shameful. So it's got me curious if I have a feminine mindset about the situation or if it's just because of my specific circumstances that I think this way.
