2-natural? As natural as "having just one sexual partner for life"natural? natural? the natural kind of "uncontrolled procreation no matter the over population existing", you mean? wait, ........ he may not mean "natural" at all, as it is defined in a dictionary, but natural as the way it follows their will
3- he can be happier cause he believes he´s doing the "right thing" but, believe me, he´s deeply frustrated and unsatisficed if he truly is gay.... you can´t force your body to deny its needs completely
