I’m Feeling Strange...an Educated Woman. I Like The Smell Of

I’m feeling strange...an educated woman. I like the smell of "me" for a few days after sex with my boyfriend (we are in our late 50's, enjoy sex...). When I urinate I can smell him (yes, I know the smell of sex, vaginal/sperm secretions normal), it makes me want him. After a couple days it goes away...I want more. When I talk to friends and ask/look online sooo...many women say they hate the smell after sex, fishy, etc...I do not have this reaction at all… Is there a biologic/psychological reason that a woman would find the smell of a man after sex intoxicating? Thinking it may be rooted in procreation...or I'm just weird! Not that I can procreate, maybe my hormones are in a latent state! Thanks for your time!
