<human>: I'm not sure if this is the right place or where to post this but I'll try to keep this short. I'm 18/f and currently single although I have had several relationships before. I've been working part time at my dads office just doing paperwork and stuff for a few months. 

My question is about my dad's boss. He is older, not sure his exact age but I'd guess early 50's. Not physically at all what I look for in a guy but I feel this combination of shyness/arousal/giddy like a little girl around him. I can't even pinpoint exactly why I feel this way but I do and it doesn't seem like its something that will just pass. He has made some pretty clear advances, and normally I would say no of course but the feelings are strong and not like any I've experienced before and so far I feel like I have just been lying to make excuses.

Condense the text into a few key points
