Iamvanosexual is an orientation on the asexual spectrum defined as someone who enjoy having sexual acts preformed on them but does not want to preform sexual act for others. Iamvanosexual people may be sex neutral or sex repulsed when is comes to preforming sexual acts.
The opposite of iamvanosexual is placiosexual.
Iamvanosexual is known as a micro-label, meaning that by saying that one is iamvanosexual it is implied that one is also asexual, or another ace-spec identity. In this case asexual is the primary sexual identity and iamvanosexual acts as a modifier, making a specific sub-category of asexuals.
