Condoms

So my boyfriend and I are thinking of having sex soon and were kind of having a hard time finding the right condoms. His dick is about seven inches long but he is really thick. (We have gotten up to the point of about having sex but then the condoms we got didn’t fit which was obviously very very frustrating lol) And I am on birth control but obviously it’s not protecting us against stds so I am wondering if any of you guys have recommendations for what brand of condoms we should use or if you think we should try to find a different size..? And I was just wondering so we didn’t have to go out and buy a bunch of random condoms to see what works
