39 [M4F] USA looking for an interesting relationship dynamic

Hello, I'm a business owner and i run my company from home but I can work A LOT. I also travel sometimes to go to marketing conferences/meet clients. This has caused some issues with past relationships where my partner feels like I'm not always the most available even though I am a great supportive bf who cares a lot about the person I'm with, I understand they have needs I can't meet sometimes.

I've put a lot of thought into my next relationship and have considered allowing my next gf to be able to sleep with other men while we are dating when I'm "unavailable", too exhausted or at times have E.D. performance issues brought on from the stress of running a business.

I know this is not a normal relationship dynamic but I've put a lot of thought into it and think it would work really well for me and my next partner. Also there is some element of a turn on in there with cuckolding as I do think it could be fun/hot to watch my partner be pleasured by someone else.

A little about me outside work I do enjoy golfing, traveling to new places, watching football during the season, reading when I have time, video games occasionally to relax, or cuddling up and watching a good show/movie with my partner.

I would prefer someone in the USA and ideally west coast as that's where I am but open to more long distance to start things and go from there.
