Is it normal to want to "rim" a man? -guys, give feedback, please?-

Honestly, serious question, I just want to know from a man's standpoint because they know what feels good and how it feels to THEM.

So here's the thing...

I'm actually going to perform it for the first time on a man Tonight. I've done it to a couple of girl friends/fellow Lady buddies and it drove them wild. The guy I'm going to do it to I'm surprised he's up for it, and to think it all started from him wanting varying nipple play a few nights ago, I confided in him that I like the idea of rimming and always wanted to do it to a guy and he said it sounded hot, I also want to try a "Rusty Trombone" too, I described it to him and getting rimmed while I give him from the back a reach around has him anticipating like crazy.

I want to do it expertly, no mess up's, but not sure if guys down there are the same/similar as women, I've always used the method/technique of fimly pressing my tongue from the vag and the anus, getting that in between spot and then licking playfully,and licking in circular motions then going a more 'lapping' method, longer tongue strokes then begin sucking on it and dipping my tongue inside and swirling it around.

I would assume doing the same to a man, instead of between the vag and anus I give 'special attention' to the "gooch/taint" area, cept maybe start with a blowjob, then teabagging, then the taint licking, then rim job and finish with probing inside while I jack him off, can any dudes tell me if this is the route to go or should I try more techniques? I think by this description, this is pretty fool proof, but idk honestly.

Also - P.s. Please don't reply saying it's gross or gay, it's inevitable, and going to happen and it's an unselfish way of getting a little kinky and provding my man with g-spot activity, showers are to be had followed by a thorough baby-wipe scenario to make sure it's not gross, tasting or just plain un-hygeinic.
