Is it normal for me to feel weird when i watch porn with my bf?

If you don't accept it, tell him that every minute he doesn't watch porn you'll give him a BJ.

Seems like he's watched so much of it that he forgot how to get turned on by a real person, I suggest that you talk to him about how it makes you feel, and explain you'd rather not.
If I were you, I wouldnt make a big deal out of it. Chances are, he heard about it from some one else and/or is feeling self-concious and wants to give you more.
Who knows, if you catch him in the right moment, he might not even want too turn on the computer! ;)

No, no and no! They should be so turned on by one another that there is no time nor inclination for porn. Each partner should be exciting. Fuck, did you need porn when you were young?

You and him should be making your own porn so to speak not having to watch it while having sex. What has this world cum to?
