I would, she will be MUCH more likely to be truly satisfied with your guys' sex life and less likely to stray out. Also means she is not even close to being a hoe, slut, or just girl that likes to fuck.
Also, you will be able to teach her right, so many girls think they know how to fuck but are so far off its impossible to turn back!
Just my opinion. Im married to a girl thats only been with 1 other partner, couldnt be happier.
HOWEVER, I would not wait to fuck until married. She may have no sex drive or bad pussy. Thats important. ;)
