I'm mtf so I can't comment on ftm from personal perspective. After starting hrt, my body & mind acts/reacts in a much more feminine way. Orgasms are more prolonged & I totally get why women scream/moan. It's like waves flushing over & through your body & you want & need to follow through it. Guys slow down to almost a stop, hold they're breath, & have an extremely intense but short lived spasm of release/pleasure. It's not like one or the other is better in general, but what's right for you. As far as getting horny, I'd rather fantasize (preferably looking at an attractive person in the flesh) in my mind than look at porn. I feel butterflies, like my mind, boobs, & bottom side are connected as opposed to a raging hard-on, I feel the blood flush to the surface all over. Guys are hardwired for visual & obvious stimulation, while women are into emotional/fantasy rather than just raw stimulation from a standstill. Most of all this a very broad & oversimplified(are there really words?) generalization. People are so different that even trying to describe feels offensive.
