If you aren't going with a cup then you need to throw down some money on some high end pants. Empire, eclipse, or dye. I can tell you from experience the lighter more comfy pants like the nxe's are missing a lot of padding in that area.
My body is a lockbox of diamonds, uranium, and assassin nobility.
I love my 2011 eclipses. You can add or remove padding and the crotch is enough to stop pain but not get in the way. Plus they have pod loops and swab pockets ABOVE the knee. I like it above for comfort reasons. They breathe well too. I found mine for $40-50 in the BST here. It is all preference though, I still love my old smart parts pants that are like sweats for PB.
The baseball style slider shorts are pretty thin and comfortable and they have a pouch for the cup. You can cut out a piece of foam or something and use that instead of a cup for more comfort. I used a thin yoga mat and just cut out a piece in the shape of a cup. A plastic cup is meant to stop a baseball, so it's too much. A piece of foam rubber does the job and you never really know it's there.
Anyway, that's what I did before I got some pants with padding in that area so no cup needed.
I have some JT Pros (2008 JT pants) and they are pretty well padded in the nuts although I don't know about you but I get shot in the nuts so infrequently that I still wouldn't wear a cup even if my pants weren't protective.

I have some Diablo 13 pants I've had for a long while. I wear khaki pants underneath because they dry up sweat really well. When it comes to taking a shot in the boys, just keep a conscious effort to protect and serve. Which comes naturally. Sometimes I pretend like every one on the field is after my junk and I keep a knee raised up. Because I'm too sexy for a cup.
Some guy at my field used to take a towel and tuck it in his pants and then fold the towel over so i would cover the jewels. He said it worked great. Or you can just get some quality pants with padding there
