Which condom to use? Guys’ opinion too!

I’m in a relatively new relationship and we’re working up to sex. He says it’s hard to finish with a condom on (which I kinda wonder if it’s part psychological). My birth control won’t be effective until the 25th, and with it still being new I don’t think I’m ready for absolutely nothing between us. He’s willing to try with a condom and isn’t being pushy at all to go without. Anyone have similar experience with their guy (or yourself, guys) and have any advice or condom suggestions?
