My Girlfriend's Purity Ring...?

That's a difficult question to answer, because I'm pretty familiar with that. I have a promise ring from my dad, and because of that it's fairly important for me to not have until marriage. When it gets very heated and both parties are turned on, it's super super difficult not to. There are times when I've wanted it really badly, but if we got close I'd suddenly get upset, and that was rough. Part of me thought something to the effect of, "why didn't he stop me? he knows I don't want to do that." It's not his fault at all, but it's a very difficult thing, and unless she tells you flat out that it's alright, I wouldn't go there. I personally don't consider oral and to be a part of that purity, so that might be something to explore to satiate your desires. Good luck!
