Apparently he can change back, mostly

Alex looked down and dropped his crusty panties. His equipment was still there, unharmed, but looking more out of place on his body.

He stripped off the hose and heels. Clearly he would need new clothes, a shower, and a drink, but first he had to know if he could change back. He sat cross-legged on the floor of the bathroom, nestling in the thick oriental rug, and concentrated. He thought hard about every male thing he could think of. He thought of bench pressing, driving fast, ignoring fashion, and beef jerky. He thought of having sex with his ex. He felt his body changing and his breasts shrinking, but he opened his eyes to look and, seeing and feeling the undeniably feminine breasts attached to his chest, felt the transformation slipping away from him. He screwed his eyes shut and concentrated again. Slowly, bit by bit, the transformation rolled back. The changes slowed down more and more.

After about 10 minutes, he opened his eyes, unsure if it was finished. His nipples were somewhat red and swollen, and his lips seemed bigger than usual, but he seemed to be himself again, at least 95%. His hair still had the same feminine style that the clothes had given him, but that was fixable.

His body was warmer and moved more easily, his skin was much less sensitive. He noticed that colors seemed muddier, and wondered if in his male form he had always been slightly colorblind. How much of the difference was from being a different person, and how much was from being a girl?

He became aware of a lingering bad taste in his mouth. Going through the cabinets, he found some ancient mouthwash and a glass and cleaned his mouth liberally. Semen tasted far better to Alice than to him, he realized.
