Mitsubishi can answer that one for you too, with this tv advertisement from the UK, concerning the bird's and the bee's and a country called Scotland. http://www.youtube.com/watch?v=tLvWfsOCxPA
it is complicated if you will not be responsible. Think about it. It is not that complicated if you know what you are doing. But if you are not ready to face the consequences then it is really COMPLICATED
And don't be in the impression that sex is not complicated after the marriage. Very few husbands are lucky if they get that
sex is something you should enjoy. It is the only time we act like animals ;o) One should never put extra effort to make sex special. It should be without any effort just like you don't put any effort to sleep, eat and laugh
I don't know what kind of sex you are having if you don't even put efforts into making it enjoyable for you and your partner. Unless you make your partner do all the "work". Its much more than sleep, eat and laugh you noob, its more like exercise that waste energy.
