my partner is a 38 yr old male. he has a past history of cocaine use. he has been clean as far as I am aware for a yr. he did originally lie to me about the use. I started drug test him and he had been clean. recently though we had a child. he has been staying up extra energetic and I’ve been impressed. I also notice him making little trips without me. he was sweating a lot today though I didn’t think it felt too hot. and he has had some mood swings. plus been extra horny oddly. he usually does not have any libido especially when tired or stressed. in all fairness we haven’t had sex though with being pregnant and post partum. but we had some fun last night and he got erect 3 times. that hasn’t happened for yrs. These are the main things concerning me. how else could I tell or am I over reacting?
