Unable to get ejaculation. Till end?

I only get erection when imaging abt woman lifts man, man sits on woman lap otherwise which watching blue films I get no erection. I m sexually attracted to physically strong women who can lift me, However while such videos where women lift men I get only erection but no ejaculation. Even I tried masturbation but never get ejaculation. However I usually get ejaculation while sleeping and dreaming about some strong woman lifting me. I know this is weird fetish but due to this I always feel that I m different than my friends and sometimes feels lonely This attractions from childhood, now my family is looking for my marriage but I can't go ahead with such thing where I can't provide sexual pleasure Can this be curable or it will be same till end? There are many people around the globe who enjoy such lift and carry fetish however I m not sure how many of them has problem like me Please consult
