No. You can be satisfied with a job well done or any other thing that you are pleased with without actually loving those things. Satisfaction is a temporary feeling of pleasure. Love lasts much longer.
Not usually. You don't love others for satisfaction, you just love them because you like something about them. Unless loving them has some connection to their satisfaction, I believe the answer is, no.
Love and satisfaction are not the same thing. If you love someone, you will like both good and bad qualities about him. Satisfaction means you are totally satisfied with something. Love contains both good and bad qualities but satisfaction contains only good quality that makes you satisfied.
