Tsext

The method of creating sexually stimulative and/or orgasmic sensations through text messaging over cellular phone. "Skillful tsext acts appear innocuous to parents or any readers of the messages other than the intended recipient(s)."

Group tsext is difficult to coordinate but not unheard of.

Oral tsexting is only possible when one or both of the involved parties are capable of operating their phone's keyboard with their mouths. This act is considered unsafe by the medical community as it can cause muscular injuries and dental disorders that, in extreme cases, leave the lovers unable to speak or eat.
