What do I do

I am in love with my girlfriend and never ever want to be without her, but the sex life is lagging and I have no idea what to do.

Let me take you through the last few days.

I had a small talk with her and she has told me she doesn't like sex any more. Now this came as a bit of a shock to me, ok since we found out she was pregnant and then once our son was born our sex life was a struggle. I always wanted to she didn't.

We used to have a great sex life before we found out about our little bundle of joy (not so little now, he's nearly 3 yrs old now) We would have sex anywhere and everywhere. All positions, we even filmed ourselves a couple of times, took pictures and experimented.

But it has come to me now having to bribe her to have sex with me, yes it sounds like prostitution and I guess technically it is but I can not see any other way of getting what I like doing apart from either going to a prostitute or having an affair both of which I don't want to do and will not do. A problem I have though is she wants wham bam thank you mam and there is no loving (well doesn't seem to be) with the whole act. I like to tease have foreplay, stroke, caress, lick, suck and finger and all the rest. She seems to not want me to do a lot of this now and it is really bugging me.

We did have a little experiment as my g/f has really gone of giving me bj's and its not down to my personal hygiene. She has been trying to build herself up to do it but what we ended up doing was just her plating 5 kisses on my which I thought was wonderful and great progress but where do I go now, do I offer her money to do it again or how soon, aaarrrgggghhhh I just don't know. Might post more later but need to sort my head out as not sure how to put down any more
