When one is talking on the phone with his (or her) partner, he may be subject to phonejaculation. Phonejaculation is when a man (or woman) is aroused by talking on the phone. One can phonejaculate when talking about another's genitals or just because he is simply turned on by his partner. Phonejaculation can be accompanied by touching on the genitals. It is still open to experimentation however so knock yourself out
"Daniel just got off the phone with Lucy and is complaining about hand-cramps. We think Daniel was busy having a phonejaculation!"
