Well, we are all different. Suppress? Not completely. But I did learn how to manage it and hold off until an appropriate opportunity arose to blow off steam. Pre-transition, I had a low T level even for a female, and my sex drive was correspondingly low. I started on a "full dose" of T straight out of the gate and became overwhelmed by my sex drive. People told me that the urges would decrease in about six months, but I needed more like a year before I saw a truly significant decrease.
During some of that period, I was working. My job requires intellectual effort; if I'd been back on the assembly line, I'm not sure how things would have gone. I sometimes found myself distracted, but I was fully capable of redirecting my thoughts when I realized that they were going astray. I just kept at it. When I got home, I took care of business. I could certainly hold off that long, although the experience wasn't exactly fun.
I suspect that I was a worst-case scenario or close to it, but I did just fine. So far, I haven't run across a trans man who wasn't able to manage.
Starting at a lowish dose and increasing gradually might be a good idea if you are concerned.
