You say:
>I am feeling some bliss too these days,

Great. Lots of people writing to say such things,
and reporting lovely 'unusual' experiences. Seems 'It' may be happening.

>but it often comes up through the second chakra so it activates the sexual
>center, but if I stay with it it moves up to the higher levels.

If it activates any centre it means that centre is not yet clear -
so may need the energy/attention.

Plus:
"When you see the up as the down, and the down as the up..."
...attributed to Jesus.

I expect you know this already.
Up and down are just perspectives - fabricated by our minds - in order to
function on a material level.
(When the planet is 'upside down' what is up and what is down?
And in relation to what? Just the field of gravity - whatever that is -
even scientists don't know.)

There are so many 'facts' that our minds 'take for granted' - when in fact,
they are not facts at all - but just ideas put into us by people who have
just made assumptions - based on other 'ignorant' people's ignorant
assumptions. Tiddly Pom.
(And these 'facts' are usually disproved later -
although it is looking pretty certain that the planet is now round.
Hard to have an up and a down on a revolving sphere eh.)

Here is another consideration.
From the East we have 'adopted' that the Kundalini rises,
and we have assumed that, that is 'A Good Thing.'
(And where does that assumption stand - when there is no good and no bad?)

In this acceptance we assume that when energy reaches a certain place the
levels through which it has passed are then clear. This may not be so.
It may be that a certain amount of energy does move, but has not yet cleared
out all the centres - and may not, in any case, move consecutively.

It maybe that the sexual centre still needs some concentrated energy in
order to complete its transformation - or maybe it doesn't need/want
transforming - it may just want some fun!

We really do not know anything - yet we assume we even know what that means.

Suggestion:
Don't interfere - in any way at all. With anything. Not even with ideas.
We just don't know - anything. So just be with what is. Not so easy eh.

Another suggestion: Have fun!

Sending you lots of love...
