For me, there are two problems with seeing a therapist:
#1 It's very expensive
#2 I don't have any experiences to discuss

I know that a therapist is going to ask me questions about past relationships and my current relationship, but the problem with that is that I've never been in a relationship at any point in my life. There really isn't a single relevant experience in my whole life. In fact, I remember being as young as 4 or 5 and being disgusted by those Calvin Klein perfume commercials (early-mid '90s). Not that they were pornographic or anything, but I do recall something about the actors expressing some desire to be with one another. Even at that age, I knew what this commercial was insinuating ("this fragrance will make you more desirable to the opposite sex"). So it seems like this aversion to physical intimacy is hard-wired into me; there's no "cause" per se.

So basically, there isn't anything for me to discuss with a therapist. No physical abuse, no witnessing physical abuse, no brainwashing, no like-minded people in my family/social circle, no bad dating experiences, etc.. And when the therapist asks me "how does your current partner feel about this" or something to that effect, the only thing I'll be able to tell them is "I don't have one".
