You should write it! There's important stories to be found in those relationships that a lot of the most polarised writers miss. If you're dating older men and maintaining friendships with them then you've got insights for younger women and for older men - and tbf, everyone else in the world. There's a reason why those relationships exist, both sexual and non-sexual and it'd be interesting to find out why. Always lovely to read your rambles in the comments and glad I didn't give you a full heart attack. :o)
