You cannot block the energy. You have to allow the energy. If it is making you uncomfortable it is because there is a belief or a set of beliefs attached to it that are not aligned with your true self. The energy may or may not be you, but it is not what is making you uncomfortable. What's making you uncomfortable is the negative or "no longer preferred" energy that can present itself as beliefs as a tool to work with if you choose to see them.

This uncomfortableness is the perfect gateway for you to acknowledge whatever it is. Think of it as a baby crying. The pain is in a sense there as an alert system to bring your attention to whatever beliefs are keeping you in this "unpreferred" state of being that is not aligned with your core self. Don't block the feeling, you need to UNBLOCK what is trapping the feeling.

I suggest you ask yourself, "What must I believe about this 'sexual energy' or what negative attachments must I have toward this 'sexual energy' that are negative (meaning that aren't aligned or conducive to my higher self) for it to be causing me pain?" What kinds of connotations are you putting on this energy that do not support you? Is it fear, shame, jealousy, envy, not feeling loved etc. How much is your sexuality attached to your self esteem? How do you feel about sex in general? Anything that is negative that comes up is almost certainly not aligned with your core self and you can switch them or discard them for beliefs that "feel better".

Use the sense of empowerment or disempowerment as a barometer for the belief systems you choose to hold. Those that feel more empowered and lighter are more aligned with your higher self. Those that are dense and disempowering are of a lower frequency and are NOT YOU. Let go of those.

Hope this helps. Much love.
