Hey... if that's your thing then it's all good. Unlike others here, you'll get no push-back from me. Everybody has a preferred type.
I suppose that I'm a bit of an anomaly too. I actually prefer women around my own age.
These type of women (over 40 or over weight) are not as much of a hot commodity and so, there's an added bonus; we are usually valued and treated like kings.
If you've got something that is working, then who cares what a bunch of internet male forum members think. In fact, it's a bit 'odd' that they are doing so much flexing among a bunch of other men.
