I suppose, but if you want the PC to have high arousal all the time, just choose both sensitive traits, naturally wet, and hair trigger. If you want the guys that way, then go with tight pussy, clever hands, and likes oral. Once someone hits max arousal they orgasm, so having it absolutely at max all the time wouldn't do anything interesting.
I mean, I get some people like to play around with various options on the fly and all, I just don't think it makes much sense with this particular game. *shrug*
The thing about the traits is, they stick with you through the entire playthrough and with them their increased/decreased speed of increasing arousal. Being able to "play around with various options on the fly", would give you a little more control as how to you're doing "things".
Are you trying to relax and take things slowly, going with your "regular" thightness or are you trying to squeeze the cum right out of him? Is he trying to get you of quick, trying to get you ready or is he teasing you? Of course, how well you're handling the pace you set, is another matter. Maybe willpower could play a role? Stronger will = you can last longer. Of course there's more to it, but yeah.
Sure, being able to control the arousal variables is a round about way of doing things, and not really give you control of the "possible" pace (by skill, thightness etc.) is being utilised, but it would be something that helps against being "forced" into a particular pace for the "entire" game.
Just because you're not naturally tight as is, doesn't mean you can't thighten up something fierce... with the expected results. It's rather unlikely that the gameplay will be extended that way soon, if at all. So, cheats would be the only way to get some more control and RP the rest.
No, she just has orgasms a lot more frequently.
...And how... is that exactly a bad thing? ;P
