Have you guys seen this? I liked what she has done. Very educational. Photos might be little disturbing for some people so viewer discretion adviced.

I particularly liked the pre and post coitus photos. It is understandable why timing is so important in ttc. Semen is slightly away from the cervix as she took these photos just before her periods as she was not ttcing.
