If you find someone fairly attractive, then the sex is not important so long as both parties are somewhat functional. "Good sex" is learnt, nobody was born with this ability. If both parties are patient and willing to go through it together, they will succeed.
Point taken, you learn together overtime and discover things. I was more referring to this specific case, where porn and its potential to affect desire/frequency may be an issue. Again, to each his own, they can do what works for them.
