What should one do if one needs to make Ghusul all the time?

asssalamu alayku respected moulana I am 17 yrs old and from 12 iwas always troubled by shaytaan .I have experienced most of the things mentioned in the book combating whisphers of shaytaan.I am able to overcome most of the issue.Now recently most of the time when I see a men I get lustful thoughts a Lustful sensation and ejeculate.I find it difficult to read namaaz as I was informed to make ghusul to obtain purity and sometimes I have to make ghusul 5 times a day.In my case does respected mufti think I could just make wudhu to obtain purity not ghusul as sometimes I am so tired of making ghusul i make my salaah qadah and if this is not the solution could you advise me as to what to do…Jazak allah
