I have a kink for mildly thick women, like some porn stars ;P. I am not sure which level of fat we are talking about. Most men and women would prefer meat, but not fat on a person from what I gathered.

Also some people carry fat in the right places that makes them look even more appealing.

Why not lose weight? It is possible for anyone regardless of age or body type or medicine usage, but requires a lot of discipline and effort. That and exercise undeniably help with bipolar disorder,. The worst case is you will have skin left over that will need surgery, but you would need to be pretty damn big for that...

I am not sure about the whole sexy clothing. Maybe he is flirting with you and wants you to wear something sexy for him? But I don't think advice to lose weight is bad at all. I just don't get it. Everyone should try to be fit.
