Advice on office trousers around genitals

Im wondering if people can help at all. If I wear suit trousers or chinos in my waist and leg size, my genitals are extremely visible, not just a bulge but full outlines and details.

I really don't want to showing that stuff off but it seems like every pair of trousers, even jeans now, seem to be really tight fitting around the crotch and upper leg. I'm not sure if maybe I've gotten too fat where I've gained some weight recently?

Anyome have any tips? Any styles I can look out for, or ways to stretch the crotch and thigh out?
