For women, tattoo location is something that requires a bit more thought than it does for men. With aging, and childbirth, women's bodies go through more changes than the bodies of most men. With those changes, the skin in certain areas can be stretched, stretch-marked, or even sag in spots over the course of time. Because of this, no matter how attractive or feminine a tattoo may be, if it is placed in one of those areas where the skin may not provide a stable canvas for the art, the tattoo may simply draw attention to an area that a woman might prefer not to be noticed.
For this reason, I suggest that women choose locations where the skin is most likely to stay relatively firm over the course of one's lifetime. Such areas include the back of the neck, upper back, on the shoulder blade area, on the lower back, and on the ankle. Other areas that have this trait include the forearms and upper arms, although these spots seem to be more popular for masculine rather than for feminine tattoos.
The belly-button area and the breasts are pretty popular areas for feminine tattoos, but these spots are particularly susceptible to a lot of changes in skin elasticity because of pregnancy and to some extent, normal aging. The lower abdomen and pubic area can also be susceptible to sagging, and so while tattoos in these areas can look very sexy, they might not be the best locations over time.
The next thing to consider is what kind of feminine tattoo you are looking for. My first suggestion is, no matter what, do NOT put the name of your lover on your body. I don't care how much in love you are right now, the hard fact of the matter is that most of the time, relationships fade a lot faster than a tattoo does!
Choosing a feminine tattoo can be a big project, as there are so many possibilities. Just make sure you choose something you actually like (don't let someone choose for you), because it's going to be with you a long time. You really don't want to rush this decision, so take plenty of time to research what you want.
If you are looking for an image such as a Celtic knot, a flower, or some other picture, simply keep looking until you find something that you really like. If you are considering an Asian letter or some kind of symbol, I recommend that you research it fully to be sure you know what it means. A single reference or a tattoo artist may give you incorrect information, and so instead of a symbol that means "gentle waters", it could very well mean "puddle of urine". Just be sure you know what it is that you are having permanently imprinted on your body.
