Yes. And I was quite horny when I went to bed. Had to satisfy myself, again. Today only mildly horny. Took my folate around 6 a.m. The l-methylfolate connection to improving endothelial nitric oxide production is clear, according to what I've read. The connection between the heart/coronary artery disease and erections, or lack of,is also clear. My echocardiogram in 2015(64 y.o.) showed some problem with the left ventrical but my ejection fraction was 55%. I was told that's good. Now, going for another echo for my new primary in preparation for repair of an umbilical hernia.(I go through doctors like water. Rare to find a good one.) Having my arteries and capillaries wide open is the goal, without medications.So the l-methyl folate made you horny?
