Hi please bear with me. Am complete novice and first time on MN!! Sorry if this is long winded and not abbreviated enough! Am having a hard time with my DS2 who started worrying before Christmas about having erections. He didn't like what happened. Explained all was normal etc, we are an open family and with 3 boys did not expect this. It was manageable with some gentle explaining and reassuring. However, over the past few weeks, has now gone to a whole new level. He worries about PE at school and having to change, swimming and now is freaking out big time about having a shower or a bath and any member of his family or otherwise seeing him naked. The worry has manifested itself in any way connected to having to change or be seen with no clothes on. For 5 days he has not showered; to start with I tried getting cross, coaxing, rewarding etc etc but he appears to be displaying real extreme anxious behavious to the point of what may be a panic attack. I have spoken to his teachers who are very helpful and sensitive and who realising there was a real problem before I even spoke to them let him wear this school uniform whilst doing PE. However he loved swimming and now the thought of doing it at school has sent him into a panic so am not sure how the teachers will get around this. It is upsetting and very worrying. He is otherwise a gentle, mature, sensitive (and at times a "worrier") and intelligent little boy who has been able to articulate that it is the worry "his penis will go big" if someone sees him. I have tried reassuring all is normal, that it happens to all boys, have told him he can go into bathroom by himself in private etc. Short of forcing him into the shower how do I get him to have a wash? And more so, how do I alleviate his fears. Would be grateful if anyone has any advice or any similar experience. Phew sorry soooo long!
