My boyfriend told me to watch porn so we can try new things out but I have no idea where to start. Help?

ALSO

I recently purchased (still waiting on it to arrive) a throat numbing spray so that I can give him better bjs because I keep having to pull away in the middle of it because I’ll almost puke and I feel bad because I should be able to pleasure my man. Have any of you tried using the numbing shit? Like does it actually work?

ALSO

Any suggestions for different positions to try are more than welcome. The ones we do the most are missionary and the one where my legs are over his shoulders and occasionally myself on top.

Thanks y’all.
