Thanks for your reply, a peek into the inner workings of a woman's mind is always welcome!

I apologise if this comes across as harsh, but personally I would never consider dating someone who is overweight

It's not harsh at all, if there's no diamond in the box I want to know that. If it's the truth, it's the truth, there's no use complaining.

It signals to me a high probability of being unable to keep up sexually (so no point in short-term dating)

Yeah, this was true for me in the past, so I spent a lot of time improving that. Now I have an above average sexual stamina, but of course I cannot just tell girls that.

a can't-be-bothered attitude towards health issues (deal-breaker in long-term dating)

The ironic thing here is that I'm obsessed about my health, it's just that I can't seem to lose weight :)

I fully understand though that my body type signals the opposite of this, so I need to adjust.
