The condoms my boyfriend and I use are hurting him? Help please.?

Well, my boyfriend and I use condoms for birth control and He says when he s in the condom (usually he pulls out, removes the condom, and s by other means) it hurts him. He never complained about wearing condoms as long as he removed it before he d, but since we tried it in the condom he says it feels terrible and yesterday we had and I could clearly see he was in pain after he had the . He says it squeezes his too much and that it's very constricting. Do we need bigger sized condoms? He measures 7-8 inches long and we use standard-sized condoms, and I always thought they were a little tight on him because it was so difficult to put on. Do we need to switch to Trojan Magnum? Or is it something else causing him pain? Thanks.
