Lower body training and tight pelvic floor

So, I have a tight pelvic floor, and my biggest issue is related to sexual dysfunction. I'm considering starting lower-body training because I've noticed my hamstrings seem atrophied (at least they look that way), and I have thin legs (I've had a desk job for over 15 years).

However, I'm worried about possibly making my condition worse.

I'd like to start doing stiff-legged deadlifts and squats, using very light weights (around 2 kg on each side), and gradually progress from there to develop and strengthen the muscles in the area.

What do you guys think about this? Where I live, there isn't a pelvic floor physiotherapist, so I'm leaning towards testing solutions and finding out on my own.
