Is it normal to take a piss in the middle of sex?

I wouldn't say it was abnormal.

There have been several time I've had to pause to go relieve my bladder during sex. I mean, it's not something that happens a lot... but it does happen.

Sometimes I wouldn't be able to finish, if you know what I mean, until I went to the bathroom.

When you gotta go you gotta go. I mean if I'm having a marathon session I might need a pee break but most of the time I pee before and sometime after.

No, and not very nice. You should go before you even start having sex.

i pee between rounds

Depends how long you are spinning it out

and how many times you c um in a session.

If you mean getting up to go take a piss, it can happen if you've been drinking a lot of fluids and simply didn't plan your evening well. If you mean urinating as a part of the act of sex for kinky fetish purposes, some people do enjoy that, yes.

no. If it happens repeatedly AND YOU DON'T KNOW WHY, you should talk to a doctor. If it's just occasionally, consider not drinking alcohol or drugging when you hope to get lucky, and even reduce water drinking And look up any prescription meds--could they cause incontinence?
