For my self I am contimplating getting ladder piercing or a PA and before I inquire with the wife I love nipple rings and think the dumbells are sexy or a vag piercing... does any one with one have an opinion of if its worth getting or expierence with a partner/lover/fling thats got pros or cons to any of them?
There is no such thing as a "vag piercing". Perhaps you just meant some sort of female genital piercing? The most common is the clitoral hood. There is also the inner or outer labia and a few other less common ones. Clitoris piercings (as opposed to clitoral hood) are rare and dangerous and require a certain type and dimension of clit. Are you saying you are going to suggest your wife get a nipple or genital piercing, or has she mentioned wanting one? If you want more info about nipple/female genital piercings let me know.
If you are just considering genital piercings because you think it will make you better in bed you may want to think harder. It will adversely impact your sex life until it is good and healed (usually around 2 months), and it may not provide you or your partner with any additional pleasure. A lot of people think that piercings are done primarily for sexual pleasure, but a many people are actually getting pierced for primarily aesthetic reasons (or some get it done thinking it will enhance pleasure and find that it doesn't - not to say it never can though, but often it seems like it's more the idea/appearance of it for those who are turned on by that, if that makes sense).
Another thing to think about is that if you are getting a genital piercing you want to make very sure you have a damn experienced piercer who isn't going to cause you some nerve damage or anything. Even with a properly done and healed piercing it can cause damage, scarring and stretching. Thin jewelry can cause tearing known as the "cheese cutter effect" and large jewelry can be uncomfortable or interfere with sex. Penis piercings may migrate, especially frenum ladder piercings which may even reject sometimes.
As to the specific piercings you mentioned for yourself:
Some women find penis piercings uncomfortable during intercourse or oral sex, and it can also impact your chances of having sex with people you are not in a long-term monogamous relationship with because they may be afraid it will increase their risks for stds or cause the condom to break (whether these fears are entirely valid or not is a whole separate issue, but either way people perceive them).
As with many piercings, there is a small risk of the jewelry becoming caught on clothing or something and being pulled or torn out.
As foreigner said, a lot of people don't end up keeping their penis piercings and if they don't remove them soon after piercing they are left with a permanent hole.
I have had sex with men with penis piercings and didn't personally find it to add anything to sex or be particularly sexy. I think a tongue piercing is sexier personally. If you are into the idea of getting your dick pierced for some other reason, like you are into BDSM/fetish or you would just like to do it for yourself, do a lot of research on it and find a really good piercer.
