I'm really well equipped (no braggin' women opinion, not mine) and I feel comfortable in them - groin area in most types of tight jeans is pretty much the same as in standard models, it's size of your ass that matters lol
If you are phatphuck you will hate them (belt area is tight, same for knee area, it's impossible to wear them with chubby legs) if you you are proportionally built, you have straight legs, muscled thighs and calves tight jeans allow you to show it off to women (they do find it attractive, it's something men since ancient times - e.g. Henry V was obsessed by showing off his muscled calves.
