Here's the lowdown - masturbation is not different from buying a hotdog in a bun because you just felt the urge to stuff your stomach. It's simply human desire, just in the form of sexual satisfaction.
The only reasons masturbation is called a bad thing are (1) bad reputation stemming from sexually-related crimes, (2) it being looked down upon certain religions and cultures, and (3) propaganda by certain public groups with ties to either religion or conservatism.
But just like any desire, it's also subject to moderation. Overdoing it, or overstepping what is considered social courtesy, civility or sanity is definitely bad.
Nope, haven't collected any. Just manga for me will do.
The closest I had to owning some figures when I won a local comic shop's promo two years ago where I was given a predetermined amount of cash that I was required to blow on their merchandise. I was really, really, really tempted to buy several of the figures in the window display - frills and all, skimpy outfits, sexually suggestive poses - but I decided at 24 I'm too old for it (and my dad might strangle me if he found out) so I just grabbed a shop basket and cherry-picked a lot of manga for myself and some US comics that I gave away to my cousins at Christmas.
