You see girls make faces all the time during anal in porn and I've never done or wanted to do anal irl myself. Curious what (taking) anal actually feels like and if it's even pleasurable.
Yeah, it really does.
The prostate comment is absolutely correct, its not too hard to find and can be reached with your own fingers.
Done in combination with penile stimulation is can HIGHLY enhance the stimulation.
Instruction may have to be given to your partner, and take it slow.
Alone, it just takes some light experimentation till you get it.
