I'm of the opinion that the majority of the good stuff should be done during foreplay, so you don't need a fancy condom.
Oh man, how in detail can a person go in this thread...
Generally, if you're going to go for ribbed, or studded or something like that, you're only going to serve to irritate her sensitive bits quicker. They're fun for a 'wham-bam' but if you plan on having prolonged intercourse, you're better off with a regular condom.
Mint is better if you blow on it, not rub it.
Flavoured condoms are ######ed, you can't mask the taste of condom. Yeah. Any others you want to know about?
