2wk since period. Shaved vagina w/ soap & next day had itchy/sensitive vagina+light discharge, brownish & no odor. Sex w/ bf = small red dots on penis?

Not related. The dots on your boyfriend's penis may or may not be related. Just to be clear, you shaved your vulva as the vagina is the inside part that doesn't have any hair. Maybe the soap caused increased itchiness and sensitivity, which could be a yeast infection. Possible boyfriend has yeast as well. If worried about std, then both of you might want to get checked, just to be sure.
