<human>: Can you give me a shortened version of the text?

Hello women of reddit! I'll keep it short 
(/r/askwomen mods suggested here instead)

I'm in my 20's and my whole life I've been gay but I still watch straight porn often (once a week, sometimes more or less).

I have never actually been with a woman beyond kissing and some other basic stuff.

Recently something happened in my life that changed my entire outlook, it's health related (no not an STD and no not contagious. But most people would agree that it's very serious and it has changed the way I view my life completely).

Since this health problem came up, I've been watching straight porn almost exclusively.

Over the past few weeks I've been looking at women on dating sites and I've decided that I would like to try just a casual sexual relationship.

As a gay guy, I've heard some women over the years tell me that they are turned off by the thought of their bf being into men.

I'm sure some women would be turned on by that but my question(s) are: should I be upfront with a girl and tell her I'm gay? Should I lie on my online profile to say I'm straight (or would bi-sexual be more appealing)? What is the best place to meet a woman for a strictly sexual relationship?

The reason I ask is because I feel like she will be able to tell that I don't quite know what I'm doing and if I am nervous and can't perform I don't want her to think I have erectile problems. Never thought I'd type that lol.

If anyone can provide some advice that would help me a lot, I have no idea how to approach this and I have almost no experience with a woman.
<bot>: life changed completely, want to try women, should I tell them I'm gay? Where is the best place to meet someone for something strictly casual?
