Most of my pants have gotten big on me, but it feels wrong to go out and buy new ones when these work fine, so I’ve been wearing them with a belt anyway. The problem is that when I sit down they bunch up around my crotch and it looks like I have a massive boner when I don’t. Obviously, I don’t want this to keep happening and am wondering if anybody knows of a way to fix this. I have relatively little expierence with sewing or tailoring but I do have access to a sewing machine. Any advice would be appreciated.
Sounds like the zipper is too long - a friend was just telling me about this pitfall since I’m planning to make a pair of pants soon.
I don’t have any first-hand experience, but this YouTube channel has some great videos about tailoring jeans. Not exactly your problem, but might at least help you understand the construction - https://youtu.be/AiYmCpDKmqk

Zippers are a little tricky to alter if you have limited sewing experience.
Here’s a guide on how to adjust the crotch, with diagrams.
I would also look into how to “take in” garments, OP! That will make them fit a little more snuggly
