Will I finally feel chills down my spine?

I was in a relationship for 2years  And we broke up a few months ago. I never really found my ex sexually attractive because he wasn't my type so I feel like the sex wasnt that great.  I recently met a guy who's more of my type..  he's slim and taller than me but a part of me is worried about opening myself to a new guy and whether I'll experience all that I had been missing..  feeling chills down my spine when he touches me. I'm just really nervous about it all
