Hi all, 30yo bi cis woman here needing some help/support/advice maybe??

So I've recently come to terms with my bisexuality after believing I was straight my entire life, and I'm now "allowing" myself to look at women in a romantic / sexual way in "real life"... But weirdly I seem to find it really difficult to even look in their direction, let along make eye contact (this isn't an issue with men, I'm pretty confident and don't feel any anxiety etc when looking at men, can read flirting signs from them etc).

But when it comes to women, I just get really anxious and just end up looking anywhere else rather than look in their general direction. Just for an example, I was out for a meal on Friday for the first time since the pandemic started last year with a friend. A group of 5/6 women came in and were seated at the table next to us, but I couldn't even bring myself to look over at them. I felt really anxious and possibly intimidated, even though they seemed like really lovely people (from overhearing snippets of their conversations). Eventually I made myself glance over and one of them was looking back at me, which instantly made me go bright red and just wanted thr ground to swallow me up...

I have no idea why this happens with women... I'm comfortable with myself (mostly) and my sexuality so why am I getting so nervous?! Has anyone else experienced something similar? And does anyone have any tips for overcoming this? Is this common for those who have recently come to terms with their sexuality at a "late" age?

Any help appreciated! Thanks all :)
