Can you feel aroused by physical touch?

If someone (could be your partner or not) touches you or initiates any kind of physical contact, can your body react even though you're not sexually attracted to them?

This has been bugging me for a while. Way before I even knew what asexuality meant, many years ago, I had a boyfriend. I remember being scared of sex, not really wanting to do it, and not seeing him that way. But I also remember feeling aroused when he kissed me.

And I wonder... is that normal for asexuals? Has me questioning stuff again lol. Is it merely physiological?
