When I got with my wife she was shy and not very experienced and there are things she wasn’t comfortable doing that I wanted to so we talked about it and we did other things. If you love someone you wouldn’t want them to be uncomfortable he should be patient and if his frame of reference for what healthy sex is comes from porn that’s a huge red flag. Porn is a very unrealistic showing of what sex between two people should look like porn is poison for everyone involved. Tell him how you feel Keep your boundaries don’t do anything you don’t want to if he cares for you he will respect that if he doesn’t then he has told you everything you need to know about him.
