With regard to sexual activity in particular, the need or desire for masturbation is commonly referred to as "sex drive" by asexuals and they disassociate it from sexual attraction and being sexual; asexuals who masturbate generally consider it to be a normal product of the human body and not a sign of latent sexuality, and may not even find it pleasurable. Some asexual men are unable to get an erection and sexual activity by attempting penetration is impossible for them. Asexuals also differ in their feelings toward performing sex acts: some are indifferent and may have sex for the benefit of a romantic partner; others are more strongly averse to the idea, though they do not typically dislike people for having sex.
