How can you prevent yourself from pre-ejaculating almost everytime you get an erection?
You can't. It is natural and individual, you can only manage it by wearing absorbent underwear (like cotton). Getting spontaneous erections usually mostly goes away with age so hopefully won't be as bothersome in a few years.
dont touch him. that is a trite response. what is required is a means to prevent the husband from achieving voluntary or involuntary erection, thus controlling his ability to ejaculate which leads to a rapid dispersal of his submissive tendencies toward his dominant Wife. Tape his penis down between his legs and make him wear very tight panties
