<human>: Could you distill the essence of the text into 1-3 sentences?

This isn't anything too crazy but I definitely need some outside input.

My fiancé is a great guy, probably the only guy I've ever really felt safe and comfortable with. He loves to sing and when we meet he was the lead in a musical in the community theater (we work full time as engineers for a large company, so he does this on the side for fun when he has time). He's very talented and definitely comes alive when he's singing on stage.

So, auditions for "Spring Awakening" are coming up. He told me they were asking him to audition for the lead and he's always enjoyed the soundtrack but never actually seen the musical so we pulled it up on YouTube and watched it together (I had never heard of it since I'm not a huge fan of musicals). I immediately NOPE'D the idea of him being the lead. I'm super uncomfortable with him even kissing a girl for a musical, and definitely would not be comfortable with a sex scene. He said he was fine with my decision and could audition for another role but didn't want to do anything that would make me uncomfortable. 

I feel bad and don't want him to resent me in the future for making him miss out on fun roles (he says he won't). I love that he's got something he's passionate about outside of work since we have soul- sucking jobs and the last thing I want is for him to become a work robot. I just really can't get comfortable with the idea of him kissing other people, even if it's just for a play or musical. Does anyone else have experience with this? Should I try to get over it or set the boundaries now? I'd really appreciate any input.
<bot>: fiance won't do musical roles that involve kissing if they make me uncomfortable, I'm afraid he'll resent me for it later.
