If by cyber-sex, you just mean sending each other graphic sexual suggestions, like..."imagine my tongue sensually travelling from your erect nipples, across the smooth desert of your tummy and finding an oasis of sweet sexual moisture at the gates of your erogenous paradise...." i'd say, forget it! Reading a book is easier!! But if there are mutual cams involved....well, it can be funny, sexy, or even quite erotic....!! But that's just my opinion!
