until bride price is paid, no sex.

Raine80:
It's not about sex as in just the physical act it's about the chemistry shared and how you relate and compliment each other which makes the sex exceptionally great ...never underestimate the importance of sex in any relationship. Even if you start getting your freak on after marriage it can put strain on a relationship if things are lacking .So back to the question ...yes it is about sex.
About guys spending and expecting favours in return there are bottom feeders who interact with likeminded individuals and there are classy individuals who know to stay away from scenarios that are only about placing a monetary value on every action. Take what you will from that.

Finally she spite out some facts

The OP asked if relationships shd always be about sex?
The answer is if the ladies too can spend equally in the relationship maybe some guys might consider having a no sex relationship because we do not trust women,we spend our money on you and some of you go give the cookie jar to another dude that doesn't spend a dime on u,so wat will you call the other guy spending a "Maga" ba? If you spend equally on the guy even if he finds out you giving the cookie jar to another guy he won't be angry. No one wants to invest in something and not get satisfaction from it. Q.e.d
