Have Relationship Questions? Ask a Counselor for Answers ASAP
Even if those are dating sites, it may be better to first establish some sort of a familiarity with one another before you let them know that. If possible, communicating with them over email/text or even Skype or phone. If these women that you'd like to know better reside in your area, after you've become familiar with them, then ask them out to meet you face to face.
A person would have to see for herself what you say is honest after you get to know each other (otherwise it sounds like a sale's pitch) and you're only trying to get to know the person.
