confuffled

Everytime I'm reading something on anal I always see the extremely emphasised rule of lots of lube. ive never exactly needed it. is that bad? even the first time my boyfriend just used a poorly lubed condom as support but it didnt hurt, I wasnt injured and it worked out Well. which confuses me (hes over average and pretty rough) since we didnt need alot of what seemed to be the most important part of it. I need almost zero foreplay or lube to handle and enjoy anal. is that abnormal?
