you could use mohs scale of hardness to find an imbetween material, however "computing stuff" would suffice. as the dude pointed out, firm would be a valid adjactive which is a mix of hard and soft.
Although there could be a kinda of penis anology, in that you can get a "semi". You know that semi state in which not "all" the blood rushes there
.That is neither flacid (soft) or erect (hard). So it could be semi-ware
