The online space is full of such personal narratives but if you are one who is not that verbose, you just have to check the boxes beside pithy descriptions which you think describe you well, and your searches for a companion is on 24 x 7 until you have found your soul-mate and so command technology to stop the search.
Convenient, isn't it? You will also find a host of online daters like Bi, queer, butch, femme in here. Each to her taste is a sort of philosophy vigorously practiced at these places but there are crowds of like minded people as well and so everyone stands a fair chance of meeting her match out there.
If you are going for an ad double-check your spelling and grammar because a poorly written ad is the biggest turn-off. And above all be positive. Your ad should project a you' that is vibrating and not just another one in the crowd. An eye-catching title, a nicely taken photo and a passion for life are the things that will get you many hits.
It is wise to go for someone who doesn't live far away from your place and who has similar interests and preferably the same political bent of mind. Look for the same age range and have a good look at the photo because appearance and how one carries herself are the two important things that contribute a lot in making or breaking a relationship.
Talking to your potential lesbian partner on phone should come after you have already corresponded to her through email or instant messenger a couple of times. Your mind will tell you if to go further or not and that generally happen when you feel an insistent urge to meet the person face to face. The advantage of talking on phone is that it tells you a lot about the lady's comfort level and mental make-up and that will help you to decide if you will be able to talk a lot or not on the first meeting.
