Well I haven't had tons of experience with condoms other than what I've used in the hobby (which was typically provided by the girl) because I was married for about 10 years. However, personally the best fits and most comfortable especially along the shaft and the base are the Magnum XL's.
I had a provider girl once try to give me a condom and I swear it must have been a tiny size version she had bought because they literally wouldn't go on. We tried 2 or 3 thinking they were defective or something. It rolled over the head part (I have a smaller head -- large at base and slightly narrower at top not extreme cone or anything just narrower), but it wouldn't go any further no matter how hard I got or how hard I tried to roll it. LOL :clapping:. I have never experienced anything like that. It would not budge. I mean literally this fucking thing wouldn't roll down any more at all. Crazy. Regular size Trojans will go on but they don't feel good and I usually can't keep an erection. Condoms suck period though unfortunately :/ Major boner kill.
