Traditional webcam sex sites may be fast and convenient, but they're also expensive.
Yes, free crowd sourced alternatives are available, but they fall short when it comes to delivering the level of intimacy that a cam to cam sex encounter delivers.
i use similar programs like Ventrilio, Gamecomm, and Teamspeak.. Microscopic little program - and all you need is each other's IP address (or register a nickname at its website). These guys are real good for their programing, but I cannot trust them for what they have done in the past.
Many of these women might prefer to use Skype for phone sex.
We've found this to be a great deal of fun as well.
There are other services that work much as Skype does, but Skype is the most widely used, meaning that your targets (kids and grandkids) may already use Skype. If you are have certain Apple products, you automatically have access to Facetime.
(You'll need an i Phone, i Pad, Mac or i Pod Touch.) Many users feel that audio/video quality on Facetime surpasses Skype, but Skype has the advantage of being accessible from almost any device.
