bedding a civvie requires that she "fancies" you, even if your just after a quick shag, what you want is irrelevant, the girl must fancy you. , you need an edge over other guys in her social circle for that to happen, you need to be fitter, better looking, and/or richer.
what you find is that a few good looking , rich guys have slept with ALOT of women, and that majority of average and below average guys have slept with virtually no women.
i myself have had 2 civvies and probably over 50 WG's.
ive certainly learnt alot since being with prossies, one of the most surprising things is that, alot of WG's who I would deem hot, attractive, would want to date in normal life, didnt float my boat when we got into bed and got intimate. "chemistry and vibe" seems to be extremely important when it comes to sex, and not just physical attractiveness.
