I think the SJ's protectiveness is AMAZINGLY romantic. I'm smitten by one!
P.S. I like to ask my ISFJ what he would do if someone tried to kill me...

I think I am very loving. If I like you, than you will know about it. If I don't then you probably won't see me around very much or I might just keep my distance. I hate conflicts, life is too short for those games.
I consider my love for my husband as deeper than openingly passionate. It's more like an old elderly couple that have loved each other since they where high school sweet hearts. I rarely demand anything from anyone other than good behavior from my kids and hopefully students, adults well it's not my business.
If my husband is busy doing something I often will come up and give him a peck on the cheek. A bear hug every once in awhile. As for my kids I will give them a kiss on the cheek in public, a hug or walk with my arm around them. However it embarrasses my 15 year old, my 11 year old and 10 year old don't mind. My 3 year old is a bit rebellious it all depends on her mood. Mostly she would rather I carry her; depending on my energy level I usually don't mind.
We may not be the artistic romantic type however we guard, stand up and protect those under our care. Ultimately known as reliable and not given into pleasure seeking behaviors.
So it really depends on the type of affection you are asking about.
