Someone said :
Define sexually active? Do you mean penetrative sex or would an oul' smooch & a bit of oral count.?
Whatever your definition is, is your definition.
This is not a survey by the national institute of accurate statistics
Some people's sexuality is made of kisses and cuddles that arouse them, or sensations that make them tingle. Some will only count penetrative sex with a climax.
Some will only be interested in porn-fed onanism, but most will define sexually active as involving a partner.
Whatever you call it is what you have been abstain-ing/-ed from.
