The Cancer man tries to hide his emotional vulnerability, but it's there for all to see.
Cancer men are often orally oriented, starting with kissing and covering the body landscape.
On the Down Side: He's emotionally manipulative, childish, defensive, rejecting, passively aggressive, brooding, self-pitying.
Everything is done with careful research, from the car he drives to the new phone he purchases. After all, Cancer men value stability above all things, and he'll take time deciding if you're safe. All this means is, he's asking you because he's thought long and hard about you as his girlfriend. Before we started dating, I told a mutual friend I wasn't sure how I felt about my now-boyfriend.
I told her I needed more time to think of him as a potential boyfriend. He didn't try to make plans with me or even text me for four months afterward. Reject them once, and they'll retreat into their shell.
The male moonchild often keeps unusually close ties to his mom. See if there are hard aspects (squares, oppositions) to his Cancer Sun or Moon.
