Interrogation!!??? My lordy, people interrogate each other for sexual kicks? Geez, that would feel like torture for me, and not good torture. Wow, LOL.
Anyway, it sounds very healthy and positive how you are asserting yourself and taking the reins in expressing your sexuality and how you want to be in relationships. Good for you. And all the best with your grad school applications! My cousin just got her doctorate after many years of grad school and I am so excited for her (she's a biologist). And my sister just started grad school for computer programming. It is such an accomplishment -- and a commendable goal.
