Could it be herpes? TMI

My boyfriend has bumps on his penis... It's a new thing they came up like maybe two months ago and he never told me about it until a month ago but they aren't going away and it looks like more have popped up. All I can think of is herpes... He just got mad and was acting like I cheated on him. But honest to God I haven't. And I got tested at the beginning of pregnancy so... His other excuse was maybe it was the toilet seat ๐Ÿ™„ but I looked it up and it said that that's not possible.... I think he may have cheated. Now I've gotta get tested ๐Ÿ˜”
Neither of us shares drinks or anything we are both scared of germs....
