Does weight matter in sex?

There is someone interested in me, she really wants to sleep with me. I don't see any problem except for two. She is mother of two and a little over weighted, that makes me feel and think that I will not be able to reach her deep down and satisfy her. I am going to break her expectations. I don't know if I am right or wrong. The second part of fear is, since I am little under weight according to my height, I feel weak and assume this is the reason I will not be able to satisfy her. Any comments?

No i dont think it should go for what u know have fun and most pf all be safe!

The answer I posted there is the same answer I would give to this question.

No being over weighted doesn't matter at all I mean my mum weighs well used to weigh 110 kilos and my father only 69 kilos and they always had sex
