Not speaking as a representative of males in general, I lived 9 of my 13 "adult years" (since turning 17) with only one person, and I can tell you that I learned more about sex, sexuality and sensuality with that one person than all of my male friends and their shorter term flings and girlfriends (and wives, in two cases). To be fair, every pairing of two people has at least a slightly different end result in the bedroom (or the couch, or the veranda, or the sink...), but you should have no worries about having "missed" something. The relationship that flourishes when you spend many years with one person makes the intimacy you share far better than whatever else lies out there, believe me.
