A man surprised his girlfriend with a proposal during a weekly testosterone shot routine.

Donavon Williams, 32, and his partner Ashley Whitfield, 29, were in their hotel in Austin, Texas, on March 14, where they attended the South by Southwest Festival.

Donavon asked if they could record Ashley administering his weekly testosterone shot to share on their social media.

And when Ashley had just finished, Donavon got down on one knee and popped the question—catching Ashley completely off guard.

Ashley, a content creator from Houston, Texas, said: "I thought he was joking at first."

"He had jokingly gotten down on one knee a few times over the last month, so I didn't take him seriously until he pulled out the ring."

"Then I was speechless."

Donavon and Ashley met on the social media app TikTok five years ago after Donavon commented on one of Ashley's videos.

The pair became friends and stayed friends for four years before their longstanding friendship eventually blossomed into a romantic relationship.

Ashley has been by Donavon's side throughout his transition, but she only started giving him his testosterone shots in December—to help ease his fear of needles.

The weekly routine has now become deeply meaningful to them both.

Ashley said: "The first time I gave him his shot, we both cried."

"It brought us even closer together."

"It's such an intimate thing—something he let me into, not something I was owed."

"So it made the proposal even more special."

Ashley and Donavon plan to enjoy their engagement before jumping into wedding plans, aiming for a year-and-a-half engagement.

Ashley said: "We're just basking in the moment right now."

"But the Pinterest boards have definitely started!"
