One thing Dr. Psych Mom forgot to mention is “sexual compatibility”. It’s not just about libido level.

If me and my partner have similar libido levels, but very different sexual styles or ways, it’s likely we won’t feel really good having sex together; it will feel odd or awkward.

The problem with having sex only after marriage, is that you’re “shopping in the dark”: you cannot really know what you’ll get, and how much you will like it.

You cannot just know that in theory: you have to experience it firsthand, to know it (not the sex per se, but the sexual chemistry with the partner).

Remember: it’s not just about the quantity (libido), it’s about the quality as well. :-)
