Sexual Arousal In Unicorns, Pegasus Or Earth Ponys

The signs of sexual arousal in all types of ponies are as follows:

Fast heartbeat

Sweating

Short breaths

Pupil dilation

Blushing

Erections in stallions and vaginal lubrication in mares

The tail rises slightly

There are also other signs of sexual arousal in Pegasus's and Unicorns

Pegasus's

A Pegasus's wings will open straight out and tense up the moment they are aroused and are called wing boners. They will not be able to fly or close their wings and any touch against them brings intense plesure. This lasts for as long as the pony is thinking about or looking at the pony or object of their arousal. This can happen for either a mare or stallion.

Unicorns

A unicorn's horn will glow brightly the moment they are aroused. The pony or object they are looking or thinking about many be transported to where they are and levitated toward them if wanted enough. They will not be able to cast any magic spell. This lasts until the pony or object is next to them but the glowing of the horn is continuous until the pony or object is not thought of or looked at. This can happen for either a mare or stallion.
