I’m absolutely the same way. With this fetish, I’m only attracted to the belly. And it’s more so why I don’t really care about pregnant porn since the belly is hardly given much focus.

It's relieving to know there's fellow members out there who have a similar mindset to myself on this. A classic saying but as least I know I'm not alone. 

If you gave me a choice of pictures between a naked pregnant woman and one in her underwear...yes, I'd take the latter. I like the 'added mystery'. That's not to say I don't like the former - I just find the latter more appealing. The same applies for videos. As long as the bare belly (even if it's just a few inches of expanded waistline) is on display in clothed pictures and videos, that's enough for me. I'll include breasts in that - I don't have much interest in them. 

As for sexy/seductive clothing... Hmm... I don't have anything against it as such, but I will say I'm not into bondage at all. I'd much choose normal clothing and regular (and slightly sexy) underwear.

When it comes to the actual porn material - my main focus remains very much on the belly. If the belly isn't on display, my interest in the content does drop off quite significantly to the point I won't bother watching and move on. I've always felt the same. Even in my late teens/early twenties.
