Advice please! :)

Si

I am newly not a virgin and I’m 21. My bf broke up with me a few days after taking my virginity. Anyways My sex drive is crazy high and I wanted to try anal I always have haha so I bought this anal toy (pic below) and I want advice on how to use it and the do’s and don’ts and also because I bought a vibrator I got gifted a bullet and I’m not sure what that is or how to use it so advice on that as well would be much appreciated! Thank you :)
