I voted no, but my stance is probably a bit different. I've never been a fan of "gaining experience," which I'm happy about since I'm happily married now. Then again, marriage wasn't much of an issue to me, the relationship was already a committed one (not a fan of needing the state to "ordain" everything I do). As for needing "practice," I say that such is, largely, BS (especially with all of the dangers that come with it). I'm not saying that, in a relationship, it's not a good idea to see how that aspect of the relationship is (especially as prevalent an aspect as it is), but the fact is that it generally gets better over time. When I first got together with my now-wife, I hadn't really been with anyone in a long time, so there was a lot of worry and tension on my part that made for some awkward situations. Once we got past that, learned more about each other, honestly, it really couldn't be any better.
And FYI, not all guys praise each other for their "scoring." Douchebags do that, every single good guy I've known usually responds to it with some measure of disgust and changes the subject entirely (and I'm not talking about a bunch of stereotypical virgin nerds here).
