It comes down to "loving them" or having bought a ridiculously expensive deluxe Swedish memory foam sleep surface you don't want to lose when you break up.

As a former asswipe, I have a little experience in such matters so I'll try to lend whatever dry cough of perspective I may have:

I'm not going to guess your age, but I'll say late 20s just to illustrate a point (but most likely not):

If you've been with someone for three years of sexy stuff (Endless Repetition) and haven't convinced them to do something as sexually ubiquitous as roll with a beej 'til completion... it isn't going to happen unless there is serious Blunt Force Trauma involved. You're either not being assertive enough with the communication or you're desiring something out of their comfort range or interest. You can remedy the communication issue easy enough... write them a letter. About swallowing. How hot it is, how much you like it, and how much you want them to do it for you. You may be surprised.

If you're not having your sexual "needs" fulfilled in your relationship, you need to really reevaluate the situation. You're getting married... do you want to long for a girl that'll gulp down copious amounts of baby batter for the rest of your life (or, more likely, divorce after 11 months)? Basic answer: No.

Regret and desire... these things suck. Turns out you've gotta dig for that gem that's great in the kitchen and doesn't mind a thumb in her ass while you drip candle wax on the small of her back. Or whatever mental happy meal you usually order late at night when it's all about you in dreamland.

100% sexual compatibility isn't required for a healthy, long lasting relationship... but anything that makes you feel like you're not getting what you want is a great way to rot your relationship from the inside out. It may lead to infidelity (that seems utterly ridiculously to me, but hey), but most likely will lead to furious masturbation and sexual long-heavy-sigh angst. You know, the kind that you let out at night in bed with her because you're not getting what you want but you're too Nice Guy to grab her by the throat, tell her how much you want her, and make her beg for you to do whatever you want.

We can live without a lot of things... but why?

"If it makes you happy..."
