Sexual compatibility is important, this I won't deny. I would
seriously reconsider marriage if sex life was non-existant. But
it's also up to us to improve the situation. The right partner
brings out the best in us, no? Sexual skill is that - a skill that
can be taught and learnt, as with attitudes, all these can be
changed.
It's a gross assumption and huge mistake to claim that nice
people are bad in bed and vice versa. Like clothes, it's all about
the right fit. And like clothes, you can never tell how good the
fit is till you try it on.
