I was watching an astrology video and it was said there that people.with Venus harsh aspects to Pluto, besides other effects, also can block sexuality and femininity. I can say that this is my case, I have Venus in Aquarius square Pluto in Capricorn, and intimacy is an issue for me until I open up, and even then, I am.not fully comfortable at all in bed.
I would like to hear if you have gone through the same experience and if you managed to feel comfortable and free in your sexuality and how did you actually do that. Also, if you have other Venus Pluto aspects, would be happy to hear about how they play in your life as well 
I don't think this is accurate. Pluto does not block things. That's Saturn.
I have the Venus Pluto square at one degrees. It is at a tight orb and without Pluto I only have one or two other squares in my chart but Pluto has about four or more squares.
It's an extremely painful aspect for me personally. So I don't want to talk about it. :).
I have Venus in Scorpio square Pluto in Leo, natally. Pluto doesn't block, its just very protective of showing emotions until it can trust a relationship. Venus/Pluto relationships can be Heaven and Hell. It's extreme. Either you're over the Moon or in the depths of despair. That is the problem with Pluto and Venus.
I only felt comfortable with sex in a relationship. I did have casual sex a few times and it always left me feeling bad about myself. Having the relationship first made me feel comfortable and free to express myself.
Venus square Pluto always thinks too deeply of things. I suppose this aspect must be hard for you because a Venus in Aquarius is not comfortable with the depths of Pluto or the rigidity of Capricorn.
My mother has the square (Taurus/Leo), she has issues expressing affection and with spending - it's always too much or not enough. She's suffocating or she's completely detached, she's overspending beyond her budget on beauty products or buying rotting fruit past its prime for half off. I never understood how she reasons it. When she puts her focus on something, it's like a lazer beam though, she goes after what she wants.
Seems like it would be dangerous in some way to express self for a Venus square Pluto, and Pluto's house is where the danger would be coming from.
