Act like you would in real life
If in doubt, the best rule of thumb is to act like you would in real life. If you wouldn’t walk into a room in RL and ask who wants to have sex, don’t walk into a virtual room and do that. It’s going to have just as bad of a result even if they are looking for the same thing. The more real you make this, the more fun it will be. It’s ok to be more forward and direct than you would be in RL. This is a fantasy but it’s a shared fantasy and we have act appropriately.
