Did I hear you correctly?  you are a CD who is planning to have SRS.   Well orgasms are always possible.  However, transsexuals don't have SRS to have orgasms; our reasons for SRS are not sexual but gender based.  Therefore, if you are a CD thinking about having an irreversible operation like SRS, please think before you act.  SRS is designed for transsexual people only, not ->-bleeped-<-s or crossdressers.  In the US there are some requirements prior to having SRS, the standards of care, psychotherapy, hormone replacement therapy, the real life test, letters of recommendation , etc, etc, etc.  Sex reassignment surgery is performed only on people who are gender dysphoric, that is people whose inner gender does not match their  birth sex.  I suggest you consult a gender therapist before taking any decisions which you may regret later.
