A fantasy for many women they have gotten to indulge in is shower sex, or in the tub, but a standard tub might be a bit crowded for that, but a shower is doable. My concern would be the hot water running out, who wants to be doing it under freezing water, so you have around 15 minutes maybe before you’re under cold water. Also lubrication can be an issue, since water would be washing away your natural lubrication.
For women during their period, shower sex is a good option, since easier clean up when things turn messy. A guy might be more apt to want to earn his red wings in the shower than out. Guys are such pussies, afraid of a little blood! Water can increase the pleasure of the moment, especially if one somehow has unlimited hot water and some lube that wouldn’t get washed away with the water, you’d be good to go in a steamy, deluxe bathroom somewhere. Bathrooms also have mirrors many rooms do not, and the allure of sex in front of a mirror is high to some, it can be visually very enticing and exciting to watch oneself get fucked from our reflection.
Bending over the sink and even sitting on the sink with your legs wrapped around your lover, there’s all kinds of options for bathroom fun. Masturbating in the shower with the shower massager for women, and some men too, is a very fun activity to incorporate into your showering routine. But a good fuck with your lover really can’t be beat!
