I am female and spend the bulk of my time on a female av.
At some point some time after I first joined
SL, during a point in my experience when I didn't feel like getting hit on by guys at the club i was going to, I chose to try something different and created a guy av. The result was a much quieter existence in which to create stuff.
Even so, a lot of what I wanted to make I wanted to sell under my main account, so I elected to just isolate myself in a sandbox to make things rather than cut off my friends' list completely.
The guy alt now only really sees the light of day on the rare occasions I have something that needs to be sized on a guy av.
