Husband said he got turned on looking at gay couple kissing

So we went out to have some drinks last night at a bar where there was a gay couple sitting being in love kissing and all first he said did you see them kissing because we come from a country where it was not normal growing up and is still a taboo. I said yeah okay then again they started making out a lil just kisses and all then my husband said I’m getting turned on looking at them I asked jokingly are you gay? He said jokingly yes just to annoy me or idk but he was laughing when saying this anyways we had a good night but i’m just wondering and want a male perspective of it what do you think is he gay? Or its normal for straight men to see gay couple kissing and getting turned on
