Sex at 35 weeks

Lily • Almost mom to Baby Lila-Rose due July 31st
Alright tmi I've made through this whole pregnancy without sex. The day of conception is seriously the last time I got some. My boyfriend (and my baby's father) went to the Dominican Republic right after I got pregnant and as I'm sure you all know that's a Zika hot spot. He's been cleared to play by a doctor for a while now and I've recently okayed it long as we're using a condom because I'm still a little paranoid about the virus. But now I'm concerned about sex inducing labor. I absolutely cannot go into labor before 37 weeks or I won't be able to deliver where and how I want to and have been planning on delivering. Should this be a legitimate concern or are we good to go?
