I know a lot of guys hate KY and other lubes but sometimes it is necessary to use it. It seems from my experience, most girls produce enough natural lube for about 8-10 mins (max) for serious pounding. Once she starts drying up, your risk for condom breakage goes way up as the friction and associated heat buildup works together to tear apart the condom.
I have become quite sensitive to the 'feel' as my dick strokes in and out of the pussy. I periodically check my condom during a session. If it feels like there is some friction/tugging, I stop to inspect condom then ask girl if she has any lube. If she does, we continue on. If she doesn't, I stop right there and then and ask for a bj/hj to finish. Besides the girls don't like to fuck dry as it does hurt them too.
If the 'feel' feels really good, like really smooth and slippery, then it is usually too good to be true and that you may have a condom breakage upon inspection.

I guess you have to remember how bareback feels like and how wearing a condom feels like and keep those thoughts in mind as you shag.
One should not really blame the girls' supply of condoms as they don't want a condom breakage either. The only reason to bring your own is that you can bring condoms that you know fit you properly esp for those bros with big ones.
If you have a condom breakage with the girl, no need to panic. Stop everything, jump together to the shower to wash everything, then have a discussion with the girl if possible, Leave her a much bigger tip than usual (a few hundreds) so that she can go to either get a checkup or buy the 'morning-after' pill to stop the possible pregnancy. Then you head to a clinic for a std checkup.
A condom breakage is costly in monetary and psychological terms. So next time when you shag, leave some brainpower for the monitoring of your sex session and be ready to stop session.
Also another accident that occurs is leaving the condom behind in the pussy after you cum. This is not necessary because of an ill-fitting condom (too large) but because you decided to leave your dick in her pussy too long as both of you enjoyed the afterglow and intimacy after you/her cum.
After your dick has cum, it will begin to shrink. If you are too slow, the condom will come off in her pussy. So guys don't tardy and use your fingers to hold base of condom as u pull out so that it all comes out fine. I had to turn down some of those 'afterglow' embraces with sauna girls that would had enhanced our relationships just so I can be sure nothing is left behind.
