Don't you think that negotiating boundaries build a strong relationship as well as attraction. You have a right to express how you feel about sleeping in the same bed as a stranger! Boundaries create intimacy and safety?

You seem to think that you have to always say "yes", but "no" lets someone know that your "yes" is real and to be trusted. Just my take on this. Rooting for you. Anxiety is normal - feel the fear and do it is my motto. But respect your own need for space as well!!!
