This is an excellent question. Some might think it is cheating and it might be if your doing it all hours of the day and lying to your SO about what you're doing. I have done it and felt a little guilty afterward. Some might consider online sex an enabler to a meeting in person. If you're typing with one hand and exchanging very intimate feelings with someone, especially over a long period of time, you could be inclined to agree to meet with them.
