Fat And Teased
Before I answer your question, FAT, I'm going to take a little stroll down Suppressed Memory Lane: I once had a "bisexual" boyfriend. (I place bisexual in quotes, Angry Bisexual Community, only because this guy wasn't bisexual. That doesn't mean other guys aren't bisexual.) My "bisexual" boyfriend liked to claim that he really wasn't that into men until I came along—I was the magical exception, the one guy who did it for him—but even then, he told people loudly at parties, he was mostly turned on by how into him I was, he wasn't that into me or my junk. (He could barely stand to look at my cock—which is why he stuffed it in his mouth or ass whenever we got naked.)
And you know what, FAT? He made disparaging comments constantly about gay men he saw on the street or on TV—gay men like the one he was with—and put me down constantly for having a much more serious case of the gay than he did. He was going to marry a woman one day, a woman with lady parts, and have a family; I was going to remain hopelessly gay all my life. He was, of course, gayer than a college wrestling team and eventually came out as gay—much to the consternation of all his friends who believed him when he said that he wasn't really that into men. (By which I mean to say, much to the consternation of absolutely no one.)
Anyway, your current boyfriend (early 60s, straight, asshole) reminded me of my old boyfriend (20, gay, asshole). A man who claims to have fallen in love with someone who he's not attracted to, or someone who disgusts him, expressly so he can belittle that person and make that person feel awful, well, that man is a complete asshole, FAT, and my first impulse is to advise you DTMFA just like I did my asshole boyfriend. But...
You say he's good to you otherwise, does loads for you, and fucks you regularly—so before you dump this motherfucker, FAT, let's consider reforming him. Say he's totally into you and into big women, just like my ex was totally into cock. But, like my ex, he's uncomfortable with his sexuality and worries about what other people think—including you, FAT, as paradoxical as that may sound. So he makes asshole comments in an effort to hide his true feelings—possibility fetishistic feelings—for big women. The asshole comments allow him to pretend that he's not into your body, just hopelessly in love with you, the person you are on the inside—which makes him one of the "good guys," i.e., a guy who isn't so shallow as to let a little thing like your weight come between you.
While I had to dump my "bisexual" boyfriend, FAT, a little shock-and-awe therapy might convince your "fatphobic" boyfriend to knock it off. You shouldn't have to put up with his comments, FAT, whether they're motivated by shame for his attraction to big fat asses or, if my theory is incorrect, by a genuine hatred for fat people. Either way, FAT, you've got to tell him—in no uncertain terms—to knock it the fuck off already. Don't be measured, don't wrap it up in "I" statements, no mewling about your feelings. Give him both barrels: "If you don't knock it the fuck off—the asshole comments, the stupid jokes—I'm going to kick your ass out, got it?" A strategic blowup or two should occur—scream, yell, smash a few things you're not all that attached to—when he slips up. Repeat until his attitude changes or his address does.
When I first met my fiancé two years ago, he was training for a marathon and had the body of a Greek god. But he seems to be losing all interest in his appearance. The other day he sent me a photo of himself (I am finishing college in another state) that made me yelp in shock because he'd gained so much weight. I don't want to dump him—the man I love is encased in that mound somewhere—but it's gotten to the point where I'm glad I'm in a long-distance relationship because it means I don't have to sleep with him. How can I communicate this in a subtle way so as not to hurt him?
The Biggest Gainer
Well, aren't you a shallow piece of shit. I mean, do you love this man for who he is or how he looks? What about the person he is on the inside?
Just kidding, TBG, I'm totally on your side. While we all eventually arrive at old and ugly—"ugly" is an entirely subjective judgment, of course, and for some of us, "body of a Greek god" counts as "ugly"—you're under no obligation to marry a man who's in a hurry to get there. Tell him that committing to you means committing to maintaining his body out of consideration for the pleasure you're expected to provide to it/take from it.
Thanks for your advice to Missing Kisses, where you explained that sometimes men can be turned on by a desire to do some post-orgasm activity but lose that desire once we've ejaculated. I have this problem with one fantasy.
For years, while fucking my wife, I've told her about how badly I want to come all over her nipples and then lick it off. She's keen on the idea and presents herself to be licked clean after I come. However, I've never been able to follow through. It's not a matter of some latent gay panic; I'm simply not turned on anymore at that point and have no desire. Is there a way around this? I'd like to complete the act at least once, if only to surprise her.
Loses Interest Quickly
There is a way around it, LIQ, but your wife will have to lead the way. So stop reading, LIQ, because the rest of this answer is for the wife's eyes only. Mrs. LIQ: You're going to have to make him do it. You're going to have to force him to follow through on all that lick-my-come-off-your-tits dirty talk. The next time he tells you he's going to lick his come off your tits, tell him that you're holding him to it: He either does it or no more pussy for him until he does. And don't make an idle threat: If he doesn't do it, don't let him fuck you again until he does. He'll do it grudgingly, and he'll hate it while he's doing it. But once he's horny again, he'll be so turned on by the thought of what you "forced" him to do that he'll totally "bring it," as the kids were only too recently saying, and fuck the living shit out of you. You're welcome.
