Zak: This is something that is not unusual at all among trans* people. For some people, sex toys can really help, since it allows them to distance themselves from their bodies or derive pleasure without touching themselves. While vibrators are often strongly associated with women, men can (and do) use them as well. Something that vibrates but doesn’t look ridiculously flashy might be useful to you. There are also other methods of masturbating without touching yourself, Fuck Yeah Sex Education has actually been covering this sort of thing recently and might be a good resource to learn more about this.
Sex can be more difficult for some people to get used to. Sometimes people can figure out what works for them with an understanding partner that they are comfortable with. It can take a lot of time to get comfortable in that situation, though, and I don’t really know what kind of advice to give you on that front. If sex and masturbation are out of the question, there are plenty of ways to sublimate your sex drive, from athletics to meditation.
*edit* Some people have written in to recommend getting a prosthetic and masturbating with it as if it were your own penis, essentially grinding against the base but only touching the prosthetic.
