Welcome to CDH! Enjoy looking around the site and meeting others.
If you don’t want to wear your breast forms you might consider a bralette. Fitting a bra can be difficult as our shoulders are broader and waists thicker. And our breasts are spaced wider apart. Some tissue may be under the arm too so you might need a garment to push the tissue forward. Often the results from a typical bra fitting aren’t what we need.
There are several CD friendly shops you might consider if there is one close to your home. Soma, Lane Bryant, Victoria Secret, and Torrid offer bras and bralettes. With COvid the associates may not be doing bra fittings but a trained associate can suggest a good size to try. Then try on a bra or bralette so you can practice. You might want a pull over style sports bra or bralette to avert eyes and hooks. Many bras now are available beginning with a B or C cup that might have cup volume too large for you (especially if you wear a large band). So the pullover style might be more favorable and supportive.
Don’t feel ashamed or nervous. The associates help men all the time. Some cross dress, others have gynomastia and need a bra’s support or run and need protection from nipple soreness. If you are very nervous or shy by all means call your nearest store to find their slower times and schedule an appointment. They’ll help you feel more comfortable.
