erections may disappear.
Archives of Sexual Behavior, VoL 15, No. 2, 1986"Suppression of spontaneous erections has been reported in many patients, but
not all, and erections usually continue to occur during periods of sexual excitement.
Incomplete suppression of sexually induced erection is not surprising
since erections still occur in men with a concentration of testosterone below
100 ng/dl (Walker et al., 1984)."

"Located around the introitus and extending into the clitoris is erectile tissue almost identical to the erectile tissue of the penis. This erectile tissue, like that of the penis, is controlled by the parasympathetic nerves that pass through the nervi erigentes from the sacral plexus to the external genitalia. In the early phases of sexual stimulation, parasympathetic signals dilate the arteries of the erectile tissue, probably resulting from release of acetylcholine, nitric oxide, and vasoactive intestinal polypeptide (VIP) at the nerve endings. This allows rapid accumulation of blood in the erectile tissue so that the introitus tightens around the penis; this aids the male greatly in his attainment of sufficient
sexual stimulation for ejaculation to occur."
Earlier, in that chapter, it is also stated,
"Thinking sexual thoughts can lead to female sexual desire, and this aids greatly in the performance of the female sexual act. Such desire is based on psychological and physiological drive, although sexual desire does increase in proportion to the level of sex hormones secreted.
Desire also changes during the monthly sexual cycle, reaching a peak near the time of ovulation, probably because of the high levels of estrogen secretion during the preovulatory period."
I am post-op, very low T, plenty of E. Sexual arousal is perhaps less frequent in nature now, but just as strong and certainly not rare. I will experience "erections" when aroused, where all the blood rushes to my genitals and it gets engorged in that one area. This can even be quite painful.
