That's definitely a personal preference! Your best bet is to ask the woman you're with!
If it's something you're into, I would definitely mention to any partner of yours that it's a fantasy you have. You can gauge their interest and see if it's something they would like to experiment with (or possibly roleplay with something like come lube if they're not comfortable with actual creampies).
I'm sure it's not every woman's cup of tea, but you'll never know without asking! It's a relatively common fantasy and I'm sure there are plenty of women who will be into it!
I have this fetish about Cumming in a very prep and licking it all out of her. Does that turn women on?
