I've read various crossdressing/crossplay forums and Googled for "erection while tucked" and various permutations thereof (usually the addition or subtraction of words such as "crossdress" and "trans"), but I haven't quite found the answer to my question.
Basically, I need to know what happens when a cross-dresser has an erection or becomes aroused while tucked--not taped. Is it painful? Will it ruin his tuck? What's going to happen, here? He'll be wearing women's panties as well as hose, if that matters. According to my research a pro can apparently learn to repress his/her erections (?!), but my character isn't quite that experienced.
Thank you so very much, and I look forward to your answers!
