Why not?
Sex is fun.
Dating in today's world sucks.
No long term commitment.
And, if you do your research, you will already know if a provider matches your sexual desire at the time.
The one or two hour marriages simply work out well.
If they change scope into overnights or long weekend things those can be nice as well.
But for me that was once upon just a few years ago.
Frankly, civie dating nowadays is a friggin zoo according to ECG's friends and a few of my mine.
