Online Hotie is asking me to send photo's... Am I a prude?

I have been out of the dating scene for 20 yrs (long term relationship & marriage) and I met a really amazing person (3 weeks) we swopped 2 photos each - so far very good. Now he is asking for photos. We do chat and we have been both seductive (subtly). Am I a prude? cause I think he is out of bounds...
