Welcome to Eccie and the best hobby ever.
I think the best advice I can give is when you're asked for screening information, provide it without argument. It's OK to ask questions for clarification but don't get into a debate about why you should give the information. If you don't feel comfortable with that ladies level of screening, politely make your apologies and move on to the next.
When writing or speaking with the ladies, always be polite and courteous, being a gentleman will get you everywhere. Don't turn an email into a porno novel or a phone call into a 900 sex chat. There will be plenty of time for that when you finally hit the sheets. LOL
Be patient. If you're still working on making your first date it may take a little while (it took me about a month to land my first) but it will happen. Like Vic said, consider joining a screening site, I use Date-Check.com. With DC you have the option of monthly, quarterly or yearly membership and they take Discover. LOL
Good luck, have fun and be safe.
