For The Bachelor's Jake Pavelka, it's pretty clear one is more important than the other. In the end, the "magic spark" he felt with Vienna was the physical chemistry he just didn't have with Tenley. In this case, the heat of a passionate bond trumps what Jake saw as a more emotional connection.
Obviously, physical attraction is an important part of any romantic relationship, and when it comes naturally, it can lead to a happy, long-lasting bond. Still, what's right for one relationship isn't right for us all. In some cases, passion can fizzle, and if there isn't emotional compatibility and understanding, the relationship could unravel. So tell me, when it comes to relationship chemistry, what's more important to you?
