You weren't rude. Def in the 4 category as your curls are small in circumference. I don't have suggestions on products because you need to work out your hair properties etc (loads on the site to tell you how) and then it's just trial and error. One feature of 4 category hair though, is that as it is so coily the natural oils don't travel down the shaft very well and so it can become very dry. The products you do use should be moisturising. I'm no expert but this is
what I have learnt from reading these forums over the years. Have a snoop around here and you'll find loads of helpful info and people.
You weren't rude at all but there are threads that are specially for asking what your hair type is. Hth.
