Asexual reproduction can be very advantageous to certain animals and protists. Organisms that remain in one particular place and are unable to look for mates would need to reproduce asexually. Another advantage of asexual reproduction is that numerous offspring can be produced without "costing" the parent a great amount of energy or time. Environments that are stable and experience very little change are the best places for organisms that reproduce asexually. A disadvantage of this type of reproduction is the lack of genetic variation . All of the organisms are genetically identical and therefore share the same weaknesses. If the stable environment changes, the consequences could be deadly to all of the individuals.
Some people feel that they are “almost asexual” or “asexual with an exception”. That is, they strongly identify with being asexual, except for a few limited or infrequent experiences of sexual attraction. Gray-asexual people fall in between asexuality and non-asexuality. In some cases, they experience sexual attraction only rarely. In others, they’re unsure if they’ve experienced it or don’t feel that they quite fit the definition of asexual in some way. Demisexual people are only capable of feeling sexual attraction after developing a strong emotional bond with someone. Demisexuality and gray-asexuality fall within what’s called the “asexual spectrum”.
