I say from personal experience. The first time I played Being a DIK I went the CHICK route and focused all my attention on Jill and Bella.
Wait, did someone so strong and rude as yourself go by his own choice in a CHICK route?
As I said, the best option is follow your heart, I think you played a route you're not comfortable expecting something that is not for the kind of person that would naturally go that route. Bella is hardly lacking scenes btw, and she has very powerful ones, but are probably more for people that would naturally enjoy a NEUTRAL/CHICK route, slowly building.
Of course if you wanted just quick sex with almost everyone the natural way would be DIK/NEUTRAL.
I just did what I felt I wanted to do and I got most of what I wanted, and it was a NEUTRAL route, I missed scenes but:
1) Not that many
2) Not many of those were the ones I was most interested in playing. And in fact, those I missed were CHICK aligned, because I missed Josy/Maya just for one fucking extra DIK choice.
I wanted to cry when I got to Pink Rose and found out that Envy would only do anal if your status was DIK. :/
I agree with something there, because DPC wanted to make you realize that you should replay the game to see missing content he makes us feel bad for not being able to chose that particular thing in that particular moment. The game would be enjoyed better if he didn't actually show you what you CAN'T chose. If you didn't know there that you could do anal you would have just enjoy the BJ thinking you went as far as possible and maybe only later, in a DIK playthrough, would have realize you could also get to do anal (you would have enjoyed the BJ a lot and then surprise, enjoyed also the anal a lot).
Unavailable choices should be hidden because they make you enjoy less what you actually get that wasn't bad at all in many cases.
