Why does male and female immune systems consider sperm cells to be enemies?

Every cell in an individual's body has specific markers so the individual's immune system will recognize it as "self". Anything that doesn't have the proper "self" markers, will be recognized as foreign and trigger an immune response (this is one of the major reason why after organ transplant, people have to be put on immuno-suppressant therapy). Sperm also have these markers, so upon insemination, it's possible for the sperm to be recognized as foreign and killed off. That usually doesn't happen because there are other components in semen that help to suppress the female's immune response (otherwise, conception would be quite rare). If you collect sperm from semen and wash away them other components, they will trigger an immune response because, again, the sperm will have certain markers that label it as foreign. Hope this helps.

Why female's immune system don't recognize semen as a foreign particles?

the female immune system does recognize semen as a foreign body that's one of the reasons males produce so many sperm. Immune system of female does recognizes semen but non selectively (First line of immune defence). That's why male discharge 100 million sperms per ml of semen (Generally, 3-4 ml semen per ejaculate). Only few hundreds of them could successfully go through hostile conditions of female reproductive tract, especially vagina. But as sperms approaches near ovum, they are recognized by fertilizing and antifertilizing mechanism to effect fertilization.
