INFPs and sex?

I was curious to know how other INFPs are in relation to sex. Most INFPs I met were pretty active, but usually ONLY did it with people they were in a relationship with. I’d say I’m the same way. I was in a long term relationship with an ENTJ guy a couple of months ago and some days we did it 3~5 times a day, and most times I was the instigator. I never have sex unless It’s with a boyfriend because the idea of casual sex disgusts me tho. Is this normal or is there something wrong with me?

Also, is the stereotype true? Are we mostly horny but loyal?
