No a body has no changes on the outer part or in physical appearance when you have regular sex. The changes that are seen or experienced are in the inner body. Weight gain is something that depends on hormone level after having and just before having sex hormones that make you happy are released by the body and yes they can be one reason for temporary weight gain.
