A bit of background. My roommate is agender and currently male. Very close friends, they're flirty and admitted to having a crush many times, wish I could date them but I'm very not into men (terminal transbian) which I've told them. But they're very twinkish and skinny, perfect clay to sculpt really. I've asked them a lot about gender and their stance is "I don't care about my body if I woke up as a woman I'd be fine and if I woke up as a man after that I'd be fine so I'll do whatever helps me do what I want in my life.". So if I could get them to have a woman's body and date them they'd arguably accept maintaining that female body to maintain our relationship.

The question is, how?
My current plan is estrogen gel while they sleep or in some skin care products but E also takes a long time and they don't have much fat to start. I want to get them on pioglitazone to quickly fatten them up into a soft fuckable bitch but it seems you can't crush the medication and you have to swallow pills whole. Are there any pioglitazone alternatives that can be administered stealthily?
