You know, she might have been in a hurry when she wrote luv instead of luv. Like someone (I'm to lazy to remember/check) said, love/luv is a big word for anyone, especially a girl who likes you to say. I had a good friend/best friend (and she still is a best friend) in 8th grade who made it clear she *really* liked me. One night, she asked me out, and I said I couldn't; I wasn't ready for that kind of relationship. It absolutely destroyed her for a while, because she poured out her soul, and I couldn't accept what she wanted. Eventually, she got over it, and accepted it. Moral: no matter how she spelled it, she still told you she really liked you.
On the other side of the coin, maybe it doesn't mean that at all. Theatre people (and many others, but I'm an actor, so i know this type for sure) say luv/love all the time. For example:
1: Hey, you know, Allison is coming into town tomorrow.
2: Oh really? Horray! She's awesome, I love her!
And my two of my best friends (two are into theater, the other is the one who likes me) say that too. For my girl theater best friend, I wrote for a birthday card: Hey! Happy bday, hope its fun! PS: No more torturing school children!
Luv, mfoley (I put my real name). She could have just choses "luv/love" as a good sign off to her card. I wouldn't worry much about it. If you like her, she likes you, and you care about each other and get along, then what she wrote in the card really isn't all that important.
Now, as for the masturbation thoughts, ah whatever. Bullies are usually seen, although very mean usually, as tough, rough, and masculine. Not that you aren't, but maybe that image gets her off? You never know. As long as it makes her feel good and it gets her off, who cares what it is?
Hope that helps! :D
