Is it normal i like ass licking being a straight male?

Well dint lick her bum hole then her vagina you will give her an infection of somesort

It is sad that the thing which you like most cannot be done with your fiance. But you can convince her by suggesting her following precautions:-
1) Taking shower before act.
2) Using dental cam to avoid direct contact between tongue and butt hole.
3) Applying enema for thoroughly cleaning of butt hole.
4) Using mouthwash after rimming.
5) Applying honey or chocolate syrup on butt hole.

So gross.......

Just another sexual act that you like. No perversion whatsoever. It's normal.

If she doesn't like it, it's off the table. If it's really important to you find a new gf. If she's more important to you and you want to keep her then live without it. It's a normal enough desire since lots of people seem into it, but she has a point poop comes from there and I can see why she's self-conscious.

just make sure she takes a shower first

Yeah, I'd say it's a pretty normal desire but not for everyone, & most importantly, apparently not for your girlfriend.

I think part of the attraction - for me at least - is that it's a little bit taboo, a little bit dirty & naughty...
Plus a lot of people enjoy it but maybe not everyone will have done it for them.

Yeah, that's normal. I love licking down there too. I do understand her feeling self-conscious, but over time maybe she will loosen up and understand that you love every part of her, even the "dirty" parts. Maybe if you ask nicely beforehand and she can shower beforehand if that makes her feel better. Maybe ask her when she's drunk... Either way, if she does let you, don't let it turn into something where you have to do this every time and you are obsessed with doing it--that will just make her feel kind of objectified.

Most women love having their arse licked.

too bad your not gay. You'd make a gay dude very happy.

Totes normal dude!

Anol is so nice the warm spunk in ure bum lovely u can lick my ass if u want and spunk in my pussy

normal i lick my wifes ass every chance i get

It's probably not ordinary but normal? for you obviously it is. For your girl it sounds as though she doesn't want you to do it, so i guess you need to stop doing it with her Maybe talk about it first ?

if you like the taste of shit hole go for it.

Lol @ "little bit dirty"...is there anything dirtier on the human body?

first of all, your girlfriend is a real lady because she admits that she poops! most women are not honest enough about their bodily functions to ever say stuff like that. if you can trust her about being honest with her shit that means you can trust her with anything. op you did the right thing, if you're gonna love a woman you better love all of her, including her bullshit. that's what a real man would do! (just make sure she takes a dump first, uses toilet paper generously, and showers before engaging in said act) *fist pumps* and if she's uncomfortable with rim jobs give her a little encouragement by saying that she can lick your butthole too if she so desires. he who giveth shall also receiveth. it's in the bible which is proven to always be right about everything.
