First off, it takes a very long time for the Capricorn to commit and to allow him or herself to fall in love. That's because the Capricorn mentality is one of stability and security, and since they expect the same out of their partner and in relationships, caution is required and full trust has to be in order before anything serious can develop.
They want a practical, logical and patient experience, over one of surprises and spontaneity, and while their show of love can be more subtle, the importance of love is not lost on them ... once they're in it, it's serious business. Caps have a great sense of loyalty, a stellar sense of humor and will take a more disciplined approach to love -- which can work for someone who tends to brush off more serious issues.
It's important to make sure a Capricorn doesn't begin to isolate him or herself at the first sign of trouble, or use work as an escape when the romantic road gets rough. Just the same, they often need to lighten up and not take things so seriously! Relationships are serious, but laughter is medicine, and sometimes the Goat could use a little extra dose. However, Capricorns are known for letting go in the bedroom and can be very sensual -- and, surprising.
