Everything was fine on my side when I first stumbled across this thread, but I'm now currently experiencing the exact same issues.
It probably has something to do with a server migration or something...
I mostly agree with seeker4 here: I don't need to know all the specifics about her sexual past (her exact 'number' and all that, which is often a misleading information anyway), but I need to know her well enough to feel secure about the whole thing.
Generally speaking however, I'm not into one-nighters or anonymous-sex and I much prefer when there's at least a baseline level of fondness/affection between my partners and I, so the girls that I usually end up having sex with rarely are perfect strangers and they often emit a pretty positive vibe in terms of 'sexual awareness' (ie. I know I can trust them because I'm quite confident that they care about their own health). If I don't get that positive vibe it's unlikely that I'd want to have sex with them anyway, they probably wouldn't even be my type in terms of personality and the 'sexual connection' just wouldn't be there. Plus, I usually keep the same partners for quite a few months and my partners often have similar sexual habits, which diminishes the risks of transmission by a considerable margin.
I've always used a condom for proper penetration, but admittedly I did indulge into 'risky oral sex' a few times through my life (while either giving or receiving), especially during the first few years of my sexual-life (from 18-20). I vividly remember one time when a girl I barely knew invited me to her place: I popped ecstasy earlier in the evening and I couldn't get a hard-on at all, so I was somehow forced to eat the pussy of a more-or-less reputable girl. I kept thinking that I was getting an STD while licking her pussy; pretty disgusting and not a fun experience at all. Luckily I've never tested positive for any STI/STD, but these risky situations have been pretty rare in my life anyway.
I seem to be in the minority regarding this, but I really don't appreciate the sight of tan-lines all that much... they just look bizarre and silly to me.
I don't mind if some body-parts are paler than others (which most women will end up like, unless they tan fully naked), but I much prefer a subtle gradation to a definitive (and awkward) 'tan-line'.
