Dear Ramnayaran:
Maybe she likes skinny men. It is a matter of personal preference. The fact that she is significantly heavier than you does not mean that she prefers a heavier man. She may prefer a skinny man.
It is a matter of personal preference. You don’t like being skinny, she may like it.
Because you are worried about your weight in the context of possible physical intimacy, it would probably be a good idea to be intimate, if you will, in very dim light, or in almost darkness. That will take care of this particular fear on your part, won’t it?
