So my husband is in theater?

He has the lead, and he has to kiss her, the other lead. I begged him to do a fake kiss but he insisted he must do the real thing. I can't bring myself to go see the play and watch him kissing this other girl. I know this doesn't bother a lot of people but it bothers me. He is the only guy I have ever kissed. He is rehersing all week and it grosses me out knowing he comes homes and kisses me after he has been kissing on her. ewww.
