me & im also saggy/cap cusp
lol i describe myself as being free spirit (saggi) & entrepreneur (cappy)
its hard fighting the opposing energies where as i am organized, i like structure sometimes i do things i question that's jusy mmy saggi side trying to make me have fun and always make sure i always have enough freedom to pursue (cappy) goals
i hope this makes sense.. your son will have to work on balancing the 2 dynamics

i am a band manager and one of my guitarists (that i'm close to) is a cap sun with sag moon. i've befriended a couple of caps in my day and this guy is NOTHING like the other caps! the most cap that u'll see in him is that he's somewhat traditional minded. he wanted to be married with kids (which he is!). he's also very protective of them. however, it only looks traditional on the surface. he married a sag woman and she is polyamorous. so while they look like a typical married couple to the world, behind the scenes they are freaks! he's very devoted to her but he's all for them having little swinger parties with friends/ppl they trust. yeah, i've been propositioned before. it sucks cuz i'm polyamorous too, and they're a hot couple, but it's a conflict of interest being as i'm his manager.

i was shocked to find out he was a cap after getting to know him. he even blew my virgo friend away (who is heavy into astrology) that knows him. his sag moon seems to trump his cap sun a lot. he is all shy and reserved at first. he tries to avoid meeting new ppl cuz it makes him nervous. however, he loosens up very quickly and when he does he is incredibly expressive. he opened up to me about his thoughts and feelings after only talking to him a couple of times. he comes to me with his problems and easily gave me his trust. he's not too worried about what others think about him either unless it involves his family in any way. so i've noticed that sags, or those with a strong sag influence, tend to really like that feeling of freedom. all sags i know are almost incapable of having monogamous relationships. free love, baby.
