He has a lump on his penis but I really like him

So! A guy I met on tinder and me started talking, the chemistry initially was great we video chatted and he looked the same as his pics. We met up and had drinks at a local restaurant, that’s when he told me he had a “mass” on his penis and that’s why he couldn’t be drafted in the army. I started to inquire about the mass and he stated that the mass was still there. I asked him had he seen anybody about that and he replied that he went to a doctor and they gave him antibiotics and it shrunk a but after he completed taking them. My thing is — should I not sleep with him because there’s a possibility he has a STD/STI? I realllllyyyy like him & he likes me and I don’t want to leave him. Getting a man is hard these days especially during the pandemic
