Why pick spam of all things? That's a low quality meat that lots of people don't like to eat unless it's their low income struggle meal. I can't imagine willingly gobbling up 1 can let alone 9.
Also it is certainly easier to eat too much than seduce your neighbors' wife but I'm not even talking about sin of coveting your neighbor's wife, even sex with someone your in a relationship with that you're not married to is considered a 'sin' even if you love your girlfriend or boyfriend you're not married to and would never cheat on them with someone else. Being gay is also deemed a sin too even though gay couples are in a committed relationship with each other, Christians deem that "lust" too and don't care that a gay couple actually love each other. Even things that don't involve actual sex are considered "sinful" such as masturbation and even looking at or thinking about a woman "lustfully" even a woman who's not married or in a relationship with anyone else.
Call me a "gooner" but a lot of the time I feel my urges for sexual pleasure are a lot harder to ignore than my urge to eat. I do like food but I also feel my urge to eat a snack doesn't feel as irresistible to masturbate to fantasies about sex with an attractive woman. I feel I can a lot easier stop myself from eating too much even when it comes to unhealthy foods I like for I do get sick to my stomach and not feel like eating more but sometimes I get so bothered by my cravings for sexual pleasure I'm just unable to ignore it. My desire for sex even pains me more than hunger when I haven't eaten for a while.
