My boyfriend masturbated to my video.. is that weird?

In today's world, I won't say it's weird. But, it indeed can endanger your life ! Be aware of the technologies and the benefits and ill-side of the same. Anytime he can record you in action and may publish over the net, if you face break-up at a later stage or use that to blackmail you. So, be alert and wise. In our culture, people are still not fully comfortable with the idea of knowing "my wife had a ual relation with another guy" or "her pics available over the net". So, be careful on those.
