Hello and welcome!

It would behoove you to get your own account, first of all.

I would advise you to learn as much as you can about what BDSM is before you start putting it into practice. Punishments, for example, are highly subjective. It sounds like angel wants more than to just be tied up and spanked once in a while, and it sounds like you want to make her happy, but does this sort of thing interest you? Consider your own limits carefully, and talk to her. It is considered healthy to build a framework within your own relationship, based on both your needs.

Some things you should ask her:

Does she have previous experience in some aspect of BDSM? (If so, she might be able to answer a lot of questions for you.)
How much of a role does she expect this to play in her life? (IE: Is it a 24/7 commitment? Is it a fun bedroom game? NOTE: This may change as the relationship progresses, and/or as you both gain more experience.)
What are her limits?
If she's had past experience, what are her turn-ons? If not, what does she fantasize about most? Likewise with how she's been punished or what gives her discomfort.

You'll think of other things to ask, and the key is to be highly communicative. It sounds like you're at a distance right now, which makes communication even more important (if that's possible), in my experience. (I was in a long-distance relationship for 3 years before we even met in person. We've been married for 5 now.)

Don't be afraid of asking questions. Don't take yourself too seriously, either. Oh, and never, ever lash out in anger. (The absolute will probably get me in trouble with others here, as it's generally accepted that there are no absolutes, but I think that one should be given an exception.) Do enjoy yourself!

Hopefully this helps somewhat!
