Alright, this issue has come up before, so let me address it now so everyone can know my position on it. Sex can be an integral part of this game, or more of a side not, just a bonus, and which of these is the case depends on the character and the player in question. Take Krathen for instance: for Krathen, sex is more than just something he does for fun, it's how he wins fights... when confronted with an enemy champion, overwhelming them with lust and taking advantage of them is among his most effective tactics. On the other hand, Jurai, one of my other characters, while certainly possessing a healthy libido, is almost all business when there is battle going on, and is not easily distracted.
Here is my opinion. It is up to each individual player to decide how much or how little sex they want this RP to include for them, as their personal preferences and character dictates. However, I have to ask then that we respect each others decisions in this regard. Having your characters be disappointed or upset with other characters who in their mind focus too much on sex is fine, but when you start getting upset enough with other players for doing so that you are considering leaving the RP, I feel the spirit of this roleplay has been lost somehow.
I can understand your frustration when certain characters *coughFeena* drop the ball so to speak by going off to get laid rather than helping out in battle, and like I said, feel free to yell at said characters in character. Just try not to get too upset about it OOC, this is a game, it's meant to be fun.
