bro,
i would think u should engage in other activities. healthy activities like meeting friends. arrange lots of appointment with friends, meet up with them, go for dining, movies, shopping, sporting etc.. whatever u like to do. dont allow urself too much free time, or else the conscious part that wants sex will knock at u.
once ur mind is away from sex, it will slowly get better. remember, u must try to endure for the initial part. one suggestion is that u can try to hang out with friends u dont talk about sexual topics with, so u will be pai seh to think of that when u hang out with them.
