I do think when people have Sensing as an inferior function it can be more difficult to identify it. Steve Vai is a perfect example of strong Se but also a secondary sort of Ni.
I feel like I'm rather pure Se and find an ongoing quiet confusion and conflict with Si. I've lived most of my life with Si users. I see them as imprinting with sensory experience for good or bad. There is a need to recreate past experiences, a detailed sense of preferences, a sense of identity based on their sensory expectations and judgements.
One positive aspect of Se for me is that past experience doesn't seem to harm me in the same way as it does Si users. I find I don't think categorically about music, movies, food, sexuality, etc. It makes one extremely adaptable in the short term but incompatible in the long term in certain ways. I find myself sexually incompatible with Si oriented people. There are too many specifics that are hard for me to remember. One partner wouldn't let me touch him in any way for a couple hours after eating. There are tons of sensitive, rigid, absolute requirements like that I can't keep track of, keep forgetting, and then keep getting my Fi hurt. I also cannot create if I think of any label, category, or judgement. I know what Vai was talking about.
