Anal?

Rainy
So my fiancé and I just had anal for our first time and we had some questions and decided to ask the community. 
1) is bleeding bad? (We used lots of lube and fingers first)
2) if he comes in me is there any chance of pregnancy?
3) is the pain normal? And for how long should it last? Will it go away after a few times?
4) do men not enjoy it if there's too much lube?
Thank you guys for all your love and support! We both use this app to find out more about love and time in the bedroom. You guys are a huge help!
