It is cheating, plain and simple. Easy to understand how eating/sucking ain't cheating because it's not intercourse and as we've been told it is and has to be. I've known men and women who've said, "Well, uh, okay, as long as y'all ain't fucking, I guess it's okay..." but having the, um, orally cheating partner having to explain why they're not going down on them. I've known men and women who were "caught in the act" and the only reason why they didn't break up or no one got beaten up or killed was because of the cheater saying, "We didn't fuck - we just gave each other head!" And, yeah, I've known men and women who went totally fucking ballistic over the act of infidelity and "we didn't fuck" isn't an excuse for cheating and things did not go well. Harder to explain this away when "Tom" has been discovered to be giving head to "Jerry" who lives next door - but some would say that as long as they're not fucking each other, eh, no harm, no foul, no cheating... but "Tom" and "Jerry" might have some explaining to do to their wives/girlfriends. If "Grace" and "Heather" have been going down on each other (and after a few glasses of wine), it's cheating if they're in a relationship but as we all know, women get pass on this... as long as they're not really lesbians who hate men and their evil penises . Some husbands/boyfriends would lose their fucking minds to know that their woman was doing this but, eh, some guys would give her a pass... as long as she's not fucking some other guy. Now, if you don't want your partner being out there giving and getting head from someone else and in direct violation of your marriage vows, you might want to consider upping your head game with them because if you don't, they just might start doing it with someone else and that might not be all that'll jump off. People cheat when their wants, needs, desires, etc., are being ignored and not taken care of. If you're doing this shit to your partner and they cheat on you, sure, they might be wrong for cheating but if you hadn't dismissed their needs or, worse, act like they're not supposed to have them with anyone other than you, well, you get to share the blame in this. Which isn't the same when a partner does everything they can to tend to their partner's needs and... nothing they can do is good enough and their partner cheats on them anyway. Maybe this is the point where a more open relationship could take place or... you can kiss the relationship goodbye.
I guess it depends on if you are eating / eaten at home......I think denial of sex could be just about as bad as cheating.
Like kdaddy says and adding my bit Kissing beyond how you would with your relatives and children, masturbating someone or mutual, touching. All cheating And I agree with twogigazh
Denial of sex is a damned good reason to cheat. I've had oral sex with men and women because their partners weren't giving them the head they needed; same for good old sex. If your partner isn't providing sex for you, what are you supposed to do? Do without it? Which is what some people do and... some people ain't trying to hear being made celibate so... eating ain't cheating. Or they hope that's how it'll be perceived when things come into the light.
The statement is only an excuse for having sex outside a closed relationship. Oral, anal, a hand job or fingering, any form of manipulation of a body part in order to bring about orgasm is cheating. The partner in the relationship is cheated out of the joy of doing it themselves. Then there's reverse cheating where the partner in the relationship isn't fulfilling or refuses to fulfill their commitment to satisfy the other sexually.
Indeed, it is an excuse and one that some people find... acceptable. I know what our definition of cheating means: It's cheating if you're a guy and you get with some other woman and... you fuck her. Now, in my own mind, before fucking her comes... some oral sex even though there are exceptions to this part... and maybe those who believe that oral sex isn't sex aren't prone to getting upset if their cheating partner says, "We didn't fuck - we just gave each other head!"
