If you're in a long distance relationship and don't live together (and one of your houses offers little 'privacy') you can't have spontaneous and/or romantic sex that is also frequent and regular?
YANBU - you can have one but not both, so it can be regular using the limited opportunities you have but therefore it won't / can't be spontaneous
YABU - yes you can have all of this, they don't have to be mutually exclusive.
