As someone who has dated / had sex with an experienced woman and with inexperienced women, the first one was much better. Inexperience women don't know how to give good head or how to use their hips in a way that doesn't crush their pelvis bone into your dick. The experienced woman could make me cum twice in half an hour and gave the best head I've ever had. Of course we all want pure virgins and knowing that you're sharing bodily fluids with another man through a 3rd party source is gross, there are still benefits to having an experience partner in bed.
tl;dr ver.: both have their benefits
