Will you mind telling me what does "soothing AF" mean?

Glad To Know There Still Are Innocent Kids Around The World 😂
AF MEANS: AS FU**, WHICH IS USED WHEN U HAVE TO TELL SOMEBODY THAT THE ACT U WROTE ABOUT OR DID IS EXTREME. In the sentence I used it to express that this Khan Academy's guy's handwriting is Very Very Much Soothing.(His handwriting makes me feel good. IDK why but it does 😅)

In cross pollination, the pollen goes to another flower of same kind or it goes to another flower of different kind or both .For ex :- papaya's pollen can go to only papaya plant or it can go to watermelon for instance , or both???

This video made me understand what a pollination is and how does it work. But still I have two questions,I will be very much helped if you can give the answers. You can see that I'm a kid, and I'm 12 years old. So the questions are:
1)Do insects help in self pollination in a plant?
2) What will happen if some pollen grains of a flower stick to a bee and that bee sits on another flower of a different species? Will cross pollination occur?
No..Pollination will not occur with a different species, the plant can be different but the speciies needs to be same.
Okay thank you very much...
And what about the first question I have asked?
Yes insects can help in self pollination but it not nessser
