Difference after sex

Someone once told me that before sex the female has all the control but as soon as you let your guard down and give yourself, (even if it is to someone you love) the male gains all the control, hence why the girl will usually wait days on end for a message, I feel this couldn't be said any better, I don't mean to offend those of you who are in relationships but I lost my virginity at age 16 to someone I hadn't known for long, and the talking didn't last long after sex, I'm now 19 and it may only be 3 years but I couldn't stress enough for those of you to wait for the right person.
