If you're really serious about finding that special someone for yourself online, then make it a priority to get a free email account specifically for that one and only purpose. This doesn't happen all the time and it's actually even quite rare. You obviously wouldn't want to use your full name as your email address either. On the other hand, you certainly shouldn't be using the actual name of someone else because that would be fraudulent. Just make something up.
Nicknames work great as email addresses too.
In other words, in your own emails, as well as with your replies - it's of utmost importance to be completely and absolutely honest in every conceivable way. This means . . . . Don't be afraid to disclose information that you may view as potentially embarrassing, degrading, or whatever. None of us are 100 percent perfect. Not you, not I, nor your potential partner.
