Asexuals may experience romantic attraction, or the desire for, fantasy of, or propensity towards romantic love, often directed at people of genders falling within an affectional orientation. Many asexuals also identify as straight, gay, or bi, using the terms in a strictly affectional sense, or alternatively as hetero-, homo-, or bi-romantic. Some asexuals identify as "aromantic." A relationship between an asexual and a sexual person may or may not involve sexual activity.
Note that asexuality is not the same as celibacy, which is the deliberate abstention from sexual activity; many asexuals do have sex, and most celibates are not asexual.
