Yeah, I've lifted since I was 14, I'm 32. I've taken the last 2 years on and off, and my stats are 5 8, around 175.
I'm around 12/13%. When I was your age, I weighed around 135. Anyway, my whole plan is to lower the bf to around 7 to 8%, while putting on some slight mass. At this point in my life I no longer care about putting on large amounts of mass.
Of course, I have to set objective goals on strength, however at this point it's more of a 'wellness/fitness', health, and aesthetic appeal regime.
