as mostly... empty profile, no info at all.

Tell more about yourself there, real or RP doesn't matter, create your character aslo in words, or people won't ever have any reason to start a talk.

Travel around, get used to SL, don't call it a game   and use search to find places for your likings.

To add to Alwin's excellent advice about profiles (very important), also work on your avatar if you haven't changed it from being a newb.  While not every girl cares about looks, a sub that wants to RP with you will most likely want a master with a good avatar and not look twice at a newb. 

A really great avatar will require you to spend some $L's, so buy them if you can.  If not, there are plenty of freebies out there.  You may not get the exact look you want as choices are limited, but you can get some great stuff to start with that you can replace as you find other stuff more to your taste or get some $L's.  The best freebies are at the shops as gifts to new people under 30 days old or as gifts to people who join the shop's group.  Avoid freebie stores as they mostly have outdated or lower quality things.  Going to shops to search for freebies vs to freebie stores will take time, but time is free.

Once you have your first non newb avatar together take a picture of yourself for your profile and replace the internet ripoff with the cheesy pickup line, which will not impress women.  You can then go to adult sims where there are places where subs looking for masters.

As far as friends, I suggest you go places where new people hang out as you will find it easiest to find friends who are also new and looking for friends.  Use search to find places like NCI (New Citizen's Incorporated) The Shelter etc.  Use newb as your key word (as well as variations of it's spelling) and hangout as your category.

NCI is also a great place to get help.  There are mentors there that can answer most of your questions and help you out with your avatar and profile building.
