I have difficulty masturbating to almost all types of porn - is something wrong?

I'd like to preface this by saying I'm really, really embarrassed to be asking this question, here or anywhere else. I'm really sorry I'm asking this...

Regardless, to explain. I am fairly young (high school age), male biologically and otherwise, and straight. I am not sexually active in terms of sex with other people, but I do masturbate. I do this once every several days, as I have found doing it more often reduces the sensation of orgasm near the point of feeling like nothing.

The issue is as follows - while I enjoy masturbation, I tend to have some difficulty doing so without porn. I do not believe I have a porn addiction, or a masturbation addiction - it has not detracted from my life or other obligations. However, even with porn, I find it rather difficult to reach orgasm, primarily because only a very sparse few types of porn hold any appeal. Generally, "hardcore" porn, with actual penetration, actively grosses me out, as does anything involving vibrators, dildos, or other sex toys. Usually, even the implication of there being any actual sex between a man and a woman is enough to make me disinterested if not actively avoid it. Generally, scenes which I do enjoy don't involve sex, or male nudity whatsoever, but place a heavy focus on females undressing or being unclothed, but not necessarily sexually.

This is very, very, very difficult to find any examples of. At some point searching becomes just scouring nude movie clip archives in the hopes of finding some obscure foreign film with scenes that fit the above description. At points I've even gone so far as to look at ecchi anime, of all things, yet that is often exaggerated to levels which ultimately distract from what I'm actually there for.

So, I am wondering:

1: Is there actually something wrong with me or my sex drive? Naturally, I recognize an internet diagnosis of anything of this sort would be unreliable at best, but if anyone believes it necessary to at least talk to a doctor about this I might choose to do so.

2: (assuming the answer to question 1 is "no") Is there a particular category/show/type of pornography I should be looking at to solve this problem?

I recognize this is a ridiculous question, but it's something I've tried to figure out for the past several years, to no avail. So, I'm sorry, but if anyone has an answer, I'd be very thankful to hear it.
