Vaginal issues after cycling

I’ve been using my parents peloton for a few weeks now. It’s been amazing for my mental and physical health esp while TTC. The other night I had to stop sex because I felt my lady parts were numb. I was not feeling aroused like normal and that never happens. Has anyone else had experience with this? I’m already very sensitive down there and have been to my obgyn about it several times. I’m worried I’m going to have to quit the spin bike. Any suggestions or advice would be appreciated.
