Actually, I prefer to suck rather than be sucked. Not that I’ll turn it down when offered, but since I have pretty severe ED, that doesn’t often happen.
Since I don’t have a full length mirror, I don’t do it often. However, I’ll occasionally lay a small mirror on the bathroom floor so I can watch myself from beneath. If I’m in a particularly horny mood, I’ll use a vibrator or dildo while I play, allowing me to watch myself getting fucked while masturbating.
