anal sex. hi. i read somewhere that anal sex between (monogamous hetrosexual ) married couples and the man cumming inside the anal cavity can cause anti sperm antibodies which leads to infertility. beside can couples who take a shower and cleaning each other bodies and anal area and the inside by medical ways get stds or cleaning is enough? . lastly after cleaning is it to practice oral to anal or that will cause transmition or oral fecal bacteria.? . also any advise is welcomed.
