I would love to see some proof of you completing these tasks, or read something interested. If the dares below are too daring then don't worry; I appreciate constructive feedback on why they are unrealistic/not doable to your standards.
• Place your ring gag in your mouth and cover it with a (medical) facemask outdoors. You can cover the strap however you want, for example with a hoody. Optionally put on sunglasses for anonymity.
• Play
Flappy Bird as long as you want. Attempting a game of Flappy Bird basically means you accept the challenge.

• Find a place (far) away from your home where you can store/lock your men's underwear. Suggestions are at work, (hidden at) a friend's or family member's house, or in a public locker. You don't have to restrit yourself to only men's underwear: any clothing for which you own a replacement women's clothing article works.
• If you're interested in posing, you have all the possibilities the internet has to offer. Whether it's a nice ass or a body, the environment/background and lighting are important as well. Perhaps a forest or a park? Or something more urban? If not, you can always get creative with the items you have at your disposal at home.
