Only a very upright seat will put any pressure at all directly on your crotch.
You want a laid back seat. Laid back seats are more aero too.
Keep in mind that seat angle is adjustable on most recumbents.
For example, the Giro on CL you linked to, with the seat laid back to a reasonable degree will place less pressure on your crotch than the Terratrike. The Rocket's seat, if positioned upright, will put some pressure there too. By the way, the link for the Rocket in your post just takes you back to the Giro ad.
But no bent will be anything like an upright bike in terms of crotch pressure. So depending on how severe the issue is, it's possible you can't screw it up in this particular respect.
