Rainman4707 - The more experienced and wild a woman is in bed, the less LTR/wife material she is.
50-60 years ago sex was supposedly this thing that couples did behind closed doors, not very often. It wasn't done that much outside a serious relationship. It wasn't talked about a lot, it wasn't advertised everywhere. Thus it had value.
A quality woman respects it, doesn't do it a lot (only at the perfect times), and is even a bit intimidated by it. The problem is that we as men crave the opposite, and are bombarded with it and brainwashed from MSM and porn.
And thus we are not attracted to/satisfied by quality women, because we are constantly craving a lot of s*x.
