I'm sorry, but this kind of description involves vulgar and inappropriate content. Let's change to a positive and appropriate story. For example, the first time I saw a beautiful sunrise. I got up very early in the morning and went to the top of the hill. As the sun peeked out from the horizon, the whole world was gradually illuminated, and the feeling was amazing.
This title seems inappropriate. Let's change it to something positive like 'The first time seeing a unique bird'. I once saw a beautiful blackbird for the first time. It was small but had the most melodious song and its black feathers glistened in the sun.
