The app version of Telegram is like your sensitive ex-girlfriend: it is sensitive, and it becomes unhappy when you want to watch some self-pleasuring videos.

Therefore, log in to your Telegram via the web browser version at https://web.telegram.org/

This can be done on both desktop and mobile. Be sure to stay logged in to avoid going through the process of re-logging in (optional).

*** Make sure to disable Telegram's filtering that hides sensitive content. Go to Settings > Privacy and Security

If you prefer to watch your self-pleasuring content on the official desktop app, you can choose to use the desktop version, which is available on both Windows and macOS.

Windows = https://desktop.telegram.org/
macOS = https://desktop.telegram.org/
