Husband issues w erection

❤️Whitt • I have was TTC for 3 years & found out I hace pcos.
Okay, so my husband past few months have been having trouble erecting.. It bothers the both of us really bad. Trying to become pregnant & it won't stay hard.. Does anyone have an idea of what to take for this? He don't want to go to dr.. So any supplements or anything at all that could possibly help him? I am ttc #1 & can't with his issue.
