The term panties refers to underwear primarily worn by women to cover their primary sexual organs. Panties also have a great appeal for men. Thus, an entire industry has established itself around this attire. There are various kinds of panties which are used to excite the sexual partner.
A slip is the most common form of relatively tight panties with an elastic band for a perfect fit. It does not have a leg joint. Especially the ornamentation and the color contribute to the highly eroticizing effect of this kind of panties.
Underpants are similar to slips with the difference that underpants have a leg joint. Underpants do not have to be very tight since they are supported by elastic bands like slips are. Mostly underpants are not considered very sexy but rather they are seen as turn offs since they do not fit very tightly and thus do not underline the female shapes. Moreover, the leg joint covers a lot of skin which is often seen as objectionable.
Thongs are likely to be seen as the embodiment of sexy underwear. The front side of a thong looks like a slip while the back is quite different since most of the behind is uncovered. Depending on the kind of thong there is only a more or less broad string of fabric which connects the front with the back of the piece of underwear. This permissiveness coupled with a certain room for fantasy appeals to men. Moreover, women often wear thongs together with low-slung jeans which are likely to show the distinctive outlines of this tantalizing underwear. Thongs can be classified into G-strings, T-strings, and V-strings.
Another very sexy form of panties are hot pants which are very tight shorts showing all the shapes of the female body. Hot pants especially highlight the proportions of the behind. Moreover, the fabric of the hot pants is likely to slip between the labia of the woman wearing them and to form a camel toe.
Recently wearing sexy panties has become more and more popular, especially among female teenagers and women in their early twenties in order to express their positive attitude. Sexy panties are worn by confident women who are flirtatious and want to look attractive.
