Last night for the first time in a long time I had a wet dream. I know it isn't usually a sin, but I'm not sure about this time. I was having a lustful dream, and the next thing I knew, I was waking up to an orgasm.
If you don't masturbate, you'll have wet dreams - short of castration, there's no way out of that.
A couple of weeks ago, I confessed to masturbation, and since then, I have not once masturbated or even had the want to do so.
Yeah, guilt trips can easily last a couple of weeks, but give it time - sooner or later, the emotional build up caused by a lack of sexual release will once again exceed the restrictive effect of your brainwashing, and you'll find yourself jacking off again - and feeling really bad afterwards, again, when the whole wretched cycle repeats.
I just want to know if this would be considered a mortal sin or not, because I'm starting to feel a little guilty, and I'm not sure why.
You're feeling guilty because you've been told your whole life that what happened is filthy and wrong, and I very much doubt if your handlers bothered to differentiate between involuntary and conscious action - it strengthens their religion if they don't make the matter very clear, in fact, since the particular meme they instilled in you thrives on uncertainty and paranoia. Anyway, as mentioned above, wet dreams are a) involuntary and b) unavoidable without some other form of sexual release. If masturbating and the inevitable result of not masturbating both count as sin, in addition to unmarried sex, then you're pretty much doomed as long as you remain single - if you get married, of course, then you can just fuck your simplistic, ignorant little brains out - better be prepared for kids, though, since contraception is also sinful in the Catholic view. In fact, viewed as a whole, the whole mechanism of sexual "sin" that you've described ultimately boils down to being compelled to marry and have regular unprotected sex as the only way to avoid eternal condemnation - which conveniently enables Catholicism, like Quiverfull, to grow and spread out of any semblance of control like the fucking malignant cancer that it is.
