That’s a tough one. I can say this – don’t expect sex to get better after you marry. If he is your fiancé now, I’m guessing the “make you cum with his dick” garbage will cease to exist eventually. That is the dumbest line by the way, but I’m sure you know that already.
I guess I need to try and be empathetic to him and you. I know a lot of guys have similar reasons they won’t eat pussy, all which are pathetic in my opinion, but it helps to understand them. Three come to mind.
First, he doesn’t really care about your orgasm. That one, unfortunately, is how he is. He is selfish, and it will manifest in a lot more ways than eating pussy. If that is the case, you may want to ask yourself if marrying this guy feels a lot more like settling. If that is the case, well, I think you know what to do.
Second, is that he is too ashamed to ask you how it needs to be done right. Can he point to a clitoris? Some guys, believe it or not, can’t. On top of that, few will insert their fingers inside you while doing it, or even know to, while sucking your clit. I suggest you communicate with him that you want it, have him watch guys who eat pussy right like Manuel Ferrara, yes James Deen (not a fan of the guy), and Nacho Vidal. Lots of male porn stars suck at eating pussy I’ve noticed.
Third, the smell. I know I know. Seems like 9th grade all over again. I personally like a woman’s scent so long as she showers everyday. If this is the reason, tell him you’d like your pussy eaten, and then take a shower with him, and afterwards, go at it. He will probably realize very quickly he was being a big pussy the whole time and then change his tune.
Last, not giving him head isn’t the solution. It just adds fuel to a fire that perpetuates the problem. I’m not saying he deserves a blowjob, but he now has ammunition for not eating your pussy. It’s a cycle that will never end if you don’t just sit down and talk about it.
That’s the key – sit down. Talk about it.
