Noticed two bugs, though unsure about the second. If your settings under UI for Button Position is set to bottom, the window for storage is invisible/ still under the buttons and off screen. The second thing is the Masturbation Exp rising, but not giving any Traits. (Unsure if there are any traits, but since everything else has a trait, I'm sure having 300 exp should probably do something.)
Oh, I see, sorry!
You can acquire Psionic skills by using the chair in the east wing of your Safe House. There are many other upgrades there as well, that you can acquire by exchanging EXP.
The southern purple section of the upgrade area pertains to Psionic abilities, so you can find several there. Hope this helps!
