Is getting aroused by my cat weird?

I (single 33m) get turned on after getting home and going to bed.

My cat is overly affectionate and will come jump on the bed and bury herself in my chest. She cuddles and purrs and puts her head in my face and sometimes she'll knead my chest too. But she's all lovey and cute. Is it weird for me to get aroused by this? Or am I just a lonely dude who finds this tiny shred of affection to be overwhelming and stimulating?
